ABSTRACT:
An oscillation system includes a pair of differentially connected oscillator transistors having a resonant tank circuit connected between collector electrodes and a current source transistor connecting both emitter electrodes to ground. The collectors and base electrodes of the oscillator transistors are cross connected to provide regenerative feedback and matched resistors connect each collector to a source of operating potential. A shunt transistor is connected to the collector of one of the oscillator transistors and a series transistor connected to their common emitters. The currents of the shunt and series transistors are combined in a second current source transistor. Control signals applied to the base of the series transistor vary the oscillator current (and thereby its frequency), and produce opposite current changes in the shunt transistor, thus maintaining the DC component of the oscillator output signal at a constant.
