Abstract

In this paper we have implemented a high speed flash ADC with low power by using threshold inverter quantization technique. The main benefit of the TIQ based CMOS flash ADC design is a simpler comparator design. The proposal is to use digital inverters as analog voltage comparators. This eliminates the requirement of high-gain differential input voltage comparators that are inherently more compound and slower than the digital inverters. The TIQ flash ADC also eliminates the need of reference voltages, which require a resistor ladder circuit. This simplicity in the comparator part provides both high speed and lower power consumption at the same time.
