ABSTRACT:
A circuit capable of simulating a transistor or a semiconductor diode with controllably adjusted voltage characteristics contains a main transistor (Q0). An input voltage (V.sub.CS) to a control system (8) is amplified with a gain set by a pair of resistors (R1 and R2) to produce a control voltage (V.sub.C) for the transistor. This downscales the forward voltage characteristics of the circuit from those of the transistor. A floating power supply (10) in series with the control electrode of the transistor permits upscaling or further downscaling of the circuit voltage range.
