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.
Claims4
An oscillator circuit having a nominal frequency, said circuit comprising
- a plurality of transistor devices each having terminals, each of the terminals on one device having a corresponding terminal on the other devices, and
- an interconnection path connecting a selected one of said terminals on one device to the corresponding terminal on the other devices, said path providing a delay which is an integer multiple of the inverse of said nominal frequency.
Dependencies are inferred from the claim text.
