【 摘 要 】

References(10)A high DC gain, wide band and fast settling fully differential amplifier is presented. The pole zero cancellation technique is used in order to increase the band width of the OTA. Also, a new technique for pole zero cancellation in three-stage OTAs is presented. The proposed OTA simulated in standard TSMC 0.18µm CMOS technology with a 1.8V power supply. The DC gain of the OTA is 85dB, the unity gain band width is 740MHz and the phase margin of 60 degree is achieved. The amplifier consumes only 18.8mW.
