Abstract
The present invention provides an alternative circuit for microwave oscillators. The invention consists of an amplifier, signal divider, filter(s), and optional limiter. The feedback path is external to the amplifier, allowing direct access and control of the loop phase and loop gain. Control of the loop gain can be used for applications such as amplitude modulation of the oscillator's output or control of the oscillator's output power. Control of the loop phase can be used to frequency modulate the oscillator or to create a voltage-controlled oscillator. Dynamic control of the loop gain with a limiter enables one to maintain linear operation throughout the oscillator. Linear operation is often desirable to eliminate the 1/f noise contributions at the frequency of operation and to enable the use of small signal s-parameters in the design and analysis.
