I'm learning the basics of Cadence OrCAD 16.6 Lite. I want to design and simulate the basic Log Amplifier and Antilog Amplifier circuits both using diode as well as transistor. I'm able to design these circuits. What values should be provided to the diode and transistor? In order to verify the simulation output, I have to calculate the output voltage theoretically, which needs the values of saturation currents for the diode and transistor. How to find these values? I have used the component DIODE from DISCRETE library and NPN BCE from TRANSISTOR library. Also tell me if I have chosen the correct components or not.
