Abstract

We propose a 4-bit 1.6GSample/s flash-A/D converter realized in a digital 0.18um 1-poly 4-metal CMOS technology. To achieve low power with good performance, we employ immanent C2MOS comparator scheme. The kickback noise is one of the most important issue in A/D comparator performance. To decrease the effect of kickback noise, here we introduce kickback neutralization technique. The designed A/D converter has an effective number of bits(ENOBs) of 3.93 while using 32mW operating at 1.6GHz.
