Abstract :
This paper presents an ultra-low power, low voltage injection locked transmitter for wireless sensor networks. The transmitter utilizes Film Bulk Acoustic Resonator (FBAR) to obtain a stable 1.9 GHz carrier and achieves 32% efficiency while delivering 0 dBm from a 280 mV supply. With 50% on-off keying, it consumes 1.6 mW and supports a maximum data rate of 50 kbps. The transmitter is implemented in a standard 130 nm CMOS process and packaged using chip-on-board techniques
