摘要：

This paper presents a new class of oscillator topology requiring only one constant gain transimpedance amplifier in the loop. An amplitude control is realized through the amplitude modulation effect within a coupled resonator system. Control of the oscillation amplitude is enabled through an external DC voltage. A frequency stability of 7.5ppb has been achieved for the proof-of-concept oscillator. This new oscillator topology can potentially be helpful for low noise and low power integrated oscillator design.
