Abstract

A low-power transmitter designed for wireless sensor networks operating in a 900-MHz ISM band has been fabricated in 0.18-mum CMOS technology. The transmitter has a power efficiency as high as 26% while radiating an output signal of -2.9 dBm. It supports both OOK and BFSK modulation. A fast frequency calibration is developed to reduce the RF tuning time down to 36 mus and thus further minimize the overall energy consumption.
