Draw curve traces for both Bipolar and CMOS transistors using this hardware and free online software. Step 1: UpLoad and Plot Curve for NPN, PNP, NMOS, and PMOS The data for the transistor curves gets uploaded into any computer and can be plotted using SciLab or Octave Step 2: Hook Up The Circuit The circuit is simple enough for a solderless breadboard. But this type of circuit tends to want to be used more ...
