摘要：Comparator is one of the most essential analog circuits required in many analog integrated circuits. It isused for the comparison between two similar or different electrical signals with reference. The design of Comparatorbecomes an essential issue when technology is scaled down. Due to the non-linear behavior of threshold voltage (VT)when the scale of technology is reduced, performance of Comparator is affected. Many versions of comparator areproposed to acquire enticing output in sub-micron and deep sub-micron technologies. The selection of particulartopology is dependent upon the requirements and application. In this we will simulate all types mentioned types ofcomparators and analyze them on the basis of different characteristics of comparator like : power dissipation , offsetvoltage , delay, speed and no. of transistor used. The simulated in HSPICE.
