Low power consumption and wide locking range triple-injection-locked frequency divider by two

Abstract

A low power consumption and wide locking range triple-injection-locked frequency divider by two is demonstrated. It consists of triple-injection which combines two features of direct injection and tail injection to enhance locking range. The measured locking range is from 10.18 GHz to 15.49 GHz (41.37%) with an injection power of 0dBm. The measured maximum output power is -3.42dBm with a tuning voltage of 2V. The power consumption of the core circuit takes 2.71mW from a 1.2V power supply.
