摘　　要：A 2.4 GHz high efficiency radio frequency （RF） transmitter for wireless body area network （WBAN） in medical applications is presented in this paper. The transmitter architecture with high energy efficiency is proposed to achieve a high data rate with low power consumption. In conventional transmitters, the oscillator and power amplifier are turned off when the transmitter sends 0. The required time for turning oscillator ON/OFF is longer than the other blocks of the transmitter. In the proposed transmitter, the low power oscillator is on all the time while the power amplifier and modulator are turned off when＂0＂data is sent. The transmitter consumes 3.2 mW at 0.5 dBm output by 285 Mbps data rate and the energy consumption per transmitted bit with 0.5 dBm output power is 10 pJ/（bit-mW）. The proposed transmitter was designed in 0.18 μm CMOS technology.A 2.4 GHz high efficiency radio frequency （RF） transmitter for wireless body area network （WBAN） in medical applications is presented in this paper.
