Abstract
A low phase noise, high frequency low voltage integrated circuit oscillator has a minimum number of live pins. It includes a three transistor current mirror defining a voltage node and a current node with an emitter follower transistor coupled between the voltage node and the current node. An output is taken from the emitter follower transistor and a tuned circuit is coupled to the voltage node. A pair of power supply pins are provided for power application to the integrated circuit and one live pin is coupled to the voltage node. A tuning circuit for affecting capacitance changes for varying the frequency of the oscillator is connectable to the voltage node. In some versions of the oscillator that use a separate crystal, additional pins are needed.
