Abstract

A highly sensitive frequency-shift keying (FSK) receiver with low power consumption that is based on the injection-locking technique is proposed for short-range wireless (SRW) applications. The proposed FSK receiver comprising a sub-mW low-noise amplifier (LNA), a trifilar transformer splitter, and an injection-locked self-oscillating mixer (SOM) is fabricated using 90 nm CMOS technology. Measurement results indicate a sensitivity of -81 dBm with a power consumption of 1.8 mW when a Bluetooth Gaussian frequency-shift keying (GFSK) modulated signal with a data rate of 1 Mb/s is received.
