Abstract
A high stability clock oscillator circuit that has no inductors in the oscillator circuit itself. In the preferred embodiment neither the collector, the base, nor the emitter of the transistor is grounded and the oscillator output is taken from the collector of the transistor. In an alternate embodiment the collector is AC grounded and the output is taken across a load resistor coupled between the emitter of the transistor and ground. The resulting oscillator is a high stability oscillator that can be used as a dock oscillator in high frequency circuits.
