Abstract
This paper presents the principles for designing
low-power transmitters for wireless sensor networks. Based on
these principles, an injection-locked transmitter is implemented
in a standard 0.13-
m CMOS process and packaged using
chip-on-board assembly. The transmitter utilizes a film bulk
acoustic resonator (FBAR) to obtain a stable carrier at 1.9 GHz.
At 0 dBm output power, the transmitter achieves an efficiency of
32% at 50 kb/s and 28% at 156 kb/s. With 50% on-off keying, the
transmitter cons
