Abstract
A 2.4 GHz full-wave AC-to-DC rectifier for wireless telemetry applications is presented. A conventional full-wave rectifier using diode-connected MOS transistors suffers from the power loss due to the intrinsic threshold voltage. In this paper, a full-wave rectifier using a transformer is presented to improve the efficiency. It has been fabricated by using the MOS transistors with medium threshold voltages in 0.18 mum CMOS process. When input power ranges from 6 dBm~12 dBm, this proposed 2.4 GHz full-wave rectifier improves the efficiency of 2.5%, compared with the conventional one.
