Abstract

This paper present a design of a 4-bit low power Flash ADC using Threshold inverting Quantization (TIQ) comparators. Unlike conventional ADC proposed work does not required resistor ladder leads to area and power saving. TIQ comparator compared input signal with internally generated switching voltage and produce thermometer code. An efficient thermometer to binary converter has been design using transmission gate based 2:1 multiplexer. The design is operated at 800mV of input frequency 1KHz, with reduced power consumption of 14.08uW and 200us delay.
