Abstract :
A coupled distributed oscillator is designed using low-loss MEMS coupled transmission lines to achieve phase noise improvement of 7dB, and an additional 2dB improvement is attributed to the MEMS transmission lines. The oscillators are fabricated in a 0.18μm 6M CMOS process, operate with a 1V supply and consume 26mW.
