ABSTRACT:
An improved oscillator circuit utilizing multiple semiconductor devices, such as field-effect transistors or bipolar transistors, is disclosed. To improve the gain of the oscillator circuit corresponding terminals on each device are interconnected via a path which provides a delay equal to an integer multiple of the inverse of the oscillator frequency. This technique can be adapted to provide an oscillator whose nominal frequency is voltage controllable and can be arranged to provide one or more output ports.
