A high efficiency AC-DC charge pump using feedback compensation technique (original) (raw)

2007 IEEE Asian Solid-State Circuits Conference, 2007

Abstract

This paper presents a high performance AC-DC charge pump for RFID tags, with the self-bias feedback and threshold compensation technique. Compared with conventional charge pump, the influence of threshold is greatly reduced and output DC voltage and power conversion efficiency is greatly improved. This proposed charge pump with 5 stages is implemented in SMIC 0.18 mum standard CMOS process. Simulation
