ANALYSIS AND SIMULATION OF DYNAMIC COMPARATOR USING 180NM AND 90NM TECHNOLOGY

In today’s world there is demand of low power and high speed application circuits for the portable devices. To meet this demand dynamic comparator play very important role. It has application mostly in Flash ADC. In my paper, I have Analyzed basic dynamic comparator with different characteristics like Propagation delay, speed, offset, ICMR, slew rate etc. I have used TSMC 180nm and TSMC 90nm technology for simulation and compared woks of both technologies. Finally with optimization of these circuits and comparison of these technologies will helped me in obtaining one circuit which will have low power, low offset and high speed CMOS voltage comparator
