This paper provides the basic simulation result for the 3 bit flash type ADC in 0.18μm technology using the NG Spice device simulator tool. It includes two stages, first stage includes 7 comparators and second stage has a thermometer encoder. The simulation is done in NG spice tool developed by university of California at Berkeley (USA).The response time of the comparator and ADC are 3.7ns and 4.9ns respectively with 50.01μw power dissipation which makes the ADC more suitable for high speed application with lower power devices.
