Abstract :
This paper presents a 1.9GHz low power transmitter for wireless sensor networks. It uses film bulk acoustic resonators (FBAR) for RF carrier generation and is co-designed with the antenna. The two-channel transmitter is 46% efficient when radiating 1.2mW from a 650mV supply. With 50% on-off keying, it consumes 1.35mW and supports data rate up till 330kbps. The 1.2times0.8mm2 transmitter is implemented in 0.13mum CMOS and is integrated into a 38times25times8.5mm3 solar powered sensor node
