Abstract

Abstract

A body biasing linearization technique is proposed to shape output spectrum mask to meet the stringent specification of the Human Body Communication (HBC) standard for Wireless Body Area Network (WBAN). Body biasing of the buffer transistors is properly designed, accordingly second-order nonlinearity coefficient is tuned so that Second order InterModulation product (IM2) at the output of buffer is cancelled. Under 0.35 m CMOS process and a supply voltage of 1.8 V, a sample HBC transmitter based on body biasing is designed. Simulation results show that an optimum of 90 dBm IIP2 can be obtained and output transmit spectral mask at 1 MHz is attenuated to be -130 dBr (dB relative to the center frequency). Compared with conventional circuits, an improvement of 23 dB spectrum attenuation is achieved, satisfying the -120 dBr requirement of IEEE 802.15.6 for WBAN.
