Abstract [en]

An active MOS diode for low voltage and low power RFID rectifiers is presented. The diode is based on the technique with internal threshold cancellation (ITC) for MOS diodes and uses a simple control scheme to minimize the diode reverse leakage so that full threshold cancellation is achieved. A theoretical background that illustrates the limitations with the ITC diode and a detailed presentation of the proposed diode with a short design procedure is included. The proposed diode is implemented in AMS 0.35 μm CMOS and simulated in Cadense Spectre in a single diode rectifier. With a diode voltage ranging from 50 to 100 mV, the proposed diode simultaneously demonstrates improved voltage and power conversion efficiency of more than 20 % each for frequencies up to 1 MHz, as compared to the MOS diode with internal threshold cancellation.
