Design of high speed op amp with different compensation technique

VDD=1.8VCL=1pFVin,cm=1.2Specification

With nulling resistor Result :UGB=334.2MHzDC gain=52dBPM=60.7Cc=1.2pFRz=250ohmPdiss=5.02mW

With source follower Result :UGB=854.83MHzDC gain=54dBPM=60.7Cc=0.6pFPdiss=5.2927mW

With current buffer Result :UGB=1.064GHzDC gain=57dBPM=60.7Cc=0.6pFPdiss=5.2015mW
