Abstract :
An antenna switch controller integrated with single-pole-multi-throw RF switches is presented. It is implemented in a 0.18 μm CMOS thin-film silicon-on-insulator (SOI) process. The proposed switch controller generates a negative voltage to enhance the linearity and power-handling capability of CMOS antenna switches, resulting in excellent RF performances. The size of the controller is 0.35 mm2 and the power consumption is 2 μA for stand-by mode and 50 μA for Rx mode.
