ABSTRACT:
An amplitude stabilized oscillator which includes an amplifier having an input, an output, and a control terminal. The amplifier has a frequency determining feedback circuit connected between its output and input terminals, and has a control voltage produced by two opposite current sources applied to its control terminal. An amplitude detector detects the oscillator output amplitude during at most one half of each oscillation period and produces an amplitude stabilizing signal which is applied to one of the two current sources.
