Abstract—in this paper, a high speed differential two stage operational amplifier has been implemented using a no-capacitor feed-forward (NCFF) compensation and negative resistance techniques in a standard 0.18 µm CMOS technology. The two stage based op-amp with NCFF compensation achieves 4.2 GHz of unity gain bandwidth for a nominal power consumption 7.7mW and exhibits 52 dB of DC gain with phase margin of 53° when driving a differential load of (2x500 fF) at a 1.8V power supply voltage. The proposed op-amp achieves a figure of merit (FOM) of 982 at 1.8 V
