Abstract :
An inductive feedback technique increases the speed of resonant circuits by 62%, allowing operation near the fT of transistors. The technique leads to a fundamental oscillator operating at 128 GHz with a power dissipation of 9 mW and a phase noise of -105 dBc/Hz at 10-MHz offset. A divide-by-two circuit based on the idea and incorporating a sampling mixer achieves a maximum speed of 125 GHz while consuming 10.5 mW. The prototypes have been fabricated in 90-nm CMOS technology.
