Abstract
The oscillator includes a high gain differential amplifier, the output of which alternately drives two sets of transistors which together provide the oscillator output signal. A first set of transistors operates during one-half cycle of the output while the other set is operating during the other half-cycle. A DC feedback path provides degenerative DC feedback to minimize the DC component of the output signal, while an AC feedback path, which includes a filter network which passes the circuit operating frequency at a 180.degree. phase shift relative to the phase of the output signal, provides regenerative AC feedback to maintain circuit oscillation.
