When Dickson charge pump is in a multi- stage cascade, body effect can significantly reduce the efficiency of the charge pump. This paper presents a new charge pump circuit. The charge pump transmits charge with a cross- coupled NMOS switch and controls the gate of the switch using the output voltage of each stage, which effectively inhibits the body effect and increases the voltage gain. Spectre results showed that, under the operating voltage of 3. 3 V, the new four level charge pump easily… CONTINUE READING
