Low power injection-locked frequency divider using native MOS

Abstract

This paper presents a 0.55V and low power divided-by-2 injection-locked frequency divider (ILFD) using native nMOS as the injection MOSFET with threshold voltage nearly equal to 0. At the injection power of 0dBm, the measured locking range is from 6.1 to 7.45 GHz. Excluding output buffers the ILFD consumes the power 0.69 mW under a standard supply of 0.55 V.
