Design Tool in TINATINA's Design Tool works with the design equations of your circuit to ensure that the specified inputs result in the specified output response. The tool requires of you a statement of inputs and outputs and the relationships among the component values. The tool offers you a solution engine that you can use to solve repetitively and accurately for various scenarios. The calculated component values are automatically set in place in the companion TINA schematic and you can check the result by simulation.
As an example, this tool can calculate feedback or other resistor and capacitor values of an amplifier in order to achieve a certain gain and bandwidth, and it can calculate component parameters of power supply circuits to meet output voltage and ripple requirements.The TINA Design Tool promotes good documentation by storing the design procedure together with the circuit. It is also very useful for semiconductor and other electronics component manufacturers to provide application circuits along with the design procedure. Let's demonstrate the use of this tool through a simple operational amplifier example. Open the Invert Gain OPA350 Test Circuit Design.TSC circuit from the Examples\Design Tool folder of TINA. In the TINA Schematic Editor the following circuit will appear:
Rf:=-Gain*Rg*(1 + 1/A)/(1+Gain/A)
Vref=[1.4998] The new values will immediately appear in the schematic editor, drawn in brown color. Press the green DC button to display the DC output voltage:
