Abstract
A differential pair, push-push oscillator for generating clocking signals. This oscillator consists of two, single transistor oscillators that both oscillate at f.sub.o with a 180.degree. phase difference. The phase difference is caused by the direct connection of the transistors' drains. A current source, connected to the transistors' drains, biases the transistors. The common drain connection also serves as an output for the differential pair, push-push oscillator. This output, a stable, relatively high power signal of frequency 2f.sub.o, is a composite of the two signals from the single transistor oscillators.
