Analog Circuit Design and Simulation with TINA-TIApplication NoteIntroductionTINATM is a Spice-based circuit simulation tool suitable for running inMicrosoft Windows Operation system. TINATM is able to precisely simulate analogcircuits and also the switch-mode power supply circuits. It is widely applied andhighly reviewed among electrical engineers, particularly analog circuits designersand application engineers. TINATM is developed by Texas Instrumentscooperated with DesignSoft,Inc. Compare to other Spice simulation software,TINATM provides the most intuitive and the easiest operating platform and view.Users usually review TINATM as the fastest running Spice simulation software.This document will introduce the operation of designing process of analogcircuits by TINATM .Part A.

Analog Circuit Design and Simulation with TINA-TIApplication NotePart B. Schematic EditingB-1 OverviewOnce the downloading and installation completed, find the programthrough Window Start menu and click on it. This will open TINA with theappearance schematic editor shown as below in Figure 3.Figure 3. Schematic Editor in TINA-TIIn Figure 3, the Schematic Editor has a empty workspace where circuitschematics are constructed. Circuit components can be selected by clicking theabove tool bar. In TINA-TI, circuit components are divided into 6 main categories(Basic, Switches, Meters, Sources, Semiconductors, Spice Macros). The tool barabove the components bar contains icons for different action of editingschematics such as copy, delete, rotate and mirror. The first row from the top isthe general tool bar with file operations and selections of analysis, test and virtualmeasurement.Chaoli AngTeam#34
Analog Circuit Design and Simulation with TINA-TIApplication NoteB-2 Adding Active and Passive ComponentsOnce a comprehensive overview of the schematic editor, we are ready tostart building circuits with TINA. The following introduces the process ofconstructing an analog circuit.We are going to construct the schematic of a 1kHz high-output sine waveoscillator circuit as an example. First of all, it is necessary to decide the keycomponents of the circuit. The OPA743 CMOS op amp is chosen by referring tothe circuit applicationspecification. This opamp need a voltagesupply ranges from3.5V to 12V tooperate, we decideto supply it with 5VAC voltage source.(1) Select the "SpiceMacros" category,click on it, you willfind the op ampsymbol, click to openthe op amp library.See Figure 4.;(2) Find Texasinstruments in"manufacturer" whichwould narrow the listFigure 4. Select Macrosdown to only TIproducts, find and click on the "OPA743", click "OK". Now, the OPA743 icon willshow on the workspace; (3) Drag the icon to appropriate position as desired.Chaoli AngTeam#35
Analog Circuit Design and Simulation with TINA-TIApplication NoteIt is easy to select components from different categories as illustrated inprevious section. These categories (Basic, Switches, Meters, Sources,Semiconductors, Spice Macros) also contains many of passive and activecomponents. Click on the schematic symbol for a particular component and dragit into position in the circuit workspace. Left clicking to set the component in thedesired position. Continuing with constructing the desire circuit schematic, a 4.7kOhm resistor needs to be added and will further be connected with upper leg ofthe op amp. To accomplish this,Figure 5. Add Passive Component(1) Click to select the "Basic" component category; See Figure 5.Chaoli AngTeam#36
Analog Circuit Design and Simulation with TINA-TIApplication Note(2) Click the resistor icon and drag the resistor to a position horizontally alignedwith the upper leg of the op amp, double-click on the resistor to open theparameter setting of it, editing to change the default value 1k to 4.7k, click "OK"to confirm. The desired resistor parameter will show adjacent to the symbol.(3) Click to select Jumper as the figure shows to avoid circuit redundancy as thejumper automatically connects to certain labeled circuit points such as the Vdd. itis necessary to keep in mind to label common jumpers in order to successfullymake the connection. This step is optional to the particular design but highlyrecommended.B-3 Schematic Arrangement and WiringAfter placing all of the needed components in appropriate positions, theprocess leads to arranging and wiring. Every component has nodes where circuitconnections are needed. These connection nodes are a red "x" dot. Wiringcomponents to each other is easily done by placing the mouse pointer over anode connection and holding the left mouse button down. A wire is drawn as themouse is moved along the circuit space grid. Release the mouse button whenthe wire reaches the intended end connection point. See Figure 6. andinstructions which shows the skills of components arranging and circuits wiring. Itis important to remember following items when arranging and wiring the circuit: Check if the cross connections in the circuit all have a black rounddot connection at them. Check the labels for each components which have jumpersconnected. Be careful about the directions of components, right click on theicon and choose rotate (Left / Right) or mirror if needed.Chaoli AngTeam#37

Make sure to leave enoughspace where the labels and parameters info text may fit in.(2) Click to select the pencil tool to draw wires connecting components, orchoose "wire" under "Insert" menu (Keyboard Combination: Ctrl Space) toperform the same task.(3) Do and check labeling.Chaoli AngTeam#38
Application NoteAnalog Circuit Design and Simulation with TINA-TIPart C. Circuit Simulation and AnalysisThe next step ready after the circuit construction is successfully completed iscircuit simulation and analysis. Selecting the Analysis menu to choose whatspecific kind of analysis is going to be performed on the built circuit. The types ofdifferent types of analyses includes AC analysis, DC analysis, transient analysis,Fourier analysis and noise analysis. The first tool shows under the Analysismenu is the Electric Rules Check (ERC) which runs schematic level errordetection with common circuit design rules. A window with ERC results and errorreports will appear (Figure 7). clicking on error reported indicated the position ofthe error point in the circuit.Chaoli AngTeam#39
Analog Circuit Design and Simulation with TINA-TIApplication NoteERC is the last step before launching any type of analysis although aquick check on circuit schematic is performed automatically by TINA at thestartup of analysis each time. Selecting and running any type of analysis, anotherwindow appears that displays different setting selections that are associated withthat particular analysis. Nominal settings are initially provided; these parametersmay be set as needed for the desired output. The first analysis performed on acircuit is generally a dc analysis. This test provides a reality check so that normaldc operating conditions can be verified. The DC Analysis function can be set tocalculate nodal voltages, provide a table of dc voltage and current results,generate a dc sweep of the circuit, or perform a temperature analysis byselecting "Mode." under "Analysis" menu and check the temperature stepping tocomplete setup and simulation. see Figure 8 for temperature analysis.Figure 8.

See Figure 9.Figure 9. Select DC Analysis(2) Once the Voltage/Current window pop-up, use the mouse as a probe andclick on a certain circuit test point. This will highlight the corresponding the item inVoltage/Current table. See Figure 10.Chaoli AngTeam#311

Analog Circuit Design and Simulation with TINA-TIApplication NoteC-2 Transient AnalysisOther than DC Analysis, AC frequency and time domain simulations mayalso be accomplished by TINA. The choices are all located under the "Analysis"menu. TINA can precisely output the AC transfer characteristic plot , time domaintransient characteristic plot and even Fourier and noise analyses results.By performing transient analysis to the example circuit, TINA outputs theresult plot shown in Figure 11. The simulation transient analysis result is alsoshown in Figure 11. The task is completed by selecting Analysis Transient,entering simulation parameters in the pop-up Transient Analysis window andfinishing up by clicking OK as shown in below.Figure 11. Transient AnalysisThe outputted plot intuitively and expectably illustrates the startup andsteady-state performance of the example circuit. Further actions on the result plotsuch as scaling, adding grids, altering color, editing labels and adding textChaoli AngTeam#313
