Information

This RTL Inverter model is one of the five benchmark circuits described in the SPICE3 Version e3 User's Manual (see information of package Spice3).

This simple RTL inverter (resistor transistor logic) circuits inverts the input voltage which means the output voltage has high potential if the input voltage has low potential and the other way round. To comprehend this behaviour the user is recommended to simulate from t=0 to t=1e-7s and observe the input voltage (VIN.p.v) and the output voltage (Q1.C.v)
