Building a circuit in Tina-TI Wein-bridge 1kHz oscillator • Select the “Spice Macros” tab. • Click on the op-amp symbol. • The op-amp list opens. Select OPA743. • U1 – OPA743 symbol appears. Drag symbol into position. • Other op-amp models may be selected using insert > macro… 5 2 1 3 4 Passive and active components are selected from symbols and lists
Building a circuit in Tina-TI Adding passive and active components • Select the “Basic” tab • Click on the desired passive component, source, jumper, generator, ground, etc. • Drag the selection into place. Click to set in position. • Double click on the selected component. An information table appears. • Enter the value and set the parameters as needed. 2 1 5 4 3 Jumpers are used to connect common circuit points without adding wires
Building a circuit in Tina-TI Arrange and wiring components • Arrange the components by clicking on the symbol and dragging them into position. • Start wiring components together by placing the pointer over the end node (small red “x”). • Click on the end node and a wire is drawn as the mouse is moved. • Release the mouse button to end a wire at another node. • Wiring function may be activated using “Insert” > wire, or the radio button pencil symbol. 5 2
Analysis Capabilities: DC • Performing a DC analysis • Click on “Analysis.” • Highlight and click on “DC Analysis.” • Click on “Calculate nodal voltages.” • The Voltages/Currents are displayed at meters/probes. • The mouse pointer becomes a probe used to probe the circuit nodes. • The probed node and measured value are shown in red, in the table. 1 2
Analysis Capabilities: Transient Transient Analysis example 1 2 5 3 4 • Click on “Analysis” • Highlight and click on “Transient” • Set start and end times, etc. • Click “ok” • Transient analysis from simulation.
Analysis Capabilities: AC Transfer Characteristics 1 3 2 • Click on “Analysis> Transient” • Set freq range, etc. Click “ok” • Transient analysis from simulation.
