7.5Vmax arbitrary waveform generator with 65nm standard CMOS under 1.2V supply voltage

Abstract

This paper presents a digitally controlled arbitrary waveform generator whose output voltage range is 0 to 7.5V under a 1.2V supply voltage. The high output voltage generation is realized using only 65nm standard MOS transistors. It consists of a voltage increasing block and a voltage decreasing block to realize stable high voltage output. Experimental results show that our waveform generator can generate arbitrary waveform, and it directly drives a MEMS structure.
