Abstract :
This paper presents an ultra-low power transmitter used for wireless sensor network (WSN) and wireless body area network (WBAN) applications. The proposed 2.4GHz direct modulation transmitter radiates 1mW with 3.88mW power consumption, and it supports OOK and ASK modulation up to 10Mbps. The novel power amplifier structure enables digital pulse-shaping to improve spectrum efficiency of OOK transmission. When applied with OOK modulation with equal probability of 1´s and 0´s, it consumes 2.3mW with an energy efficiency of 0.23nJ/bit/mW. The transmitter is implemented in a 90nm CMOS technology and packaged in a QFN56 package.
