Abstract

In this paper, a flash type A/D converter using Variable Threshold Logic circuit is designed and is layonted by double metal CMOS 2 um design rule. Comparator and register string which is the basic elements of a general flash type A/D converter are substituted by simple comparator circuit which is slightly modified from cmos inverter.
