On the Modeling of Automatic Gain Control in SPICE

Design process of any electronic analog application comprise several steps. One of the essential steps is a computer simulation, usually performed via SPICE or similar simulation software. When the application being designed is a sinusoidal oscillator, the whole task is little bit different, because besides the oscillator circuit, it is also necessary to consider Automatic Gain Control (AGC) circuitry. The paper is focused on a novel and effective way on how to simulate AGC circuitry during the design of a sinusoidal oscillator
