IP개요 In this paper, a low-power broadband feed-forward operational amplifier (OPAMP) adopting current-reuse technique is proposed. By combining a feed-forward amplifier with lowfrequency two-stage voltage gain amplifier, the proposed OPAMP obtains required phase margin without Miller compensation. It achieves broadband frequency response by removing Miller resistor and capacitor. The proposed OPAMP obtains an extra low frequency voltage gain by adopting current-reuse technique at low frequency
two-stage amplifier. It has improved unity-gain frequency with 1storder common-mode feed-back loop. The proposed low-power broadband feed-forward OPAMP is designed in 65-nm CMOS process. It achieves a DC gain of 62.26 dB and an unity-gain frequency of 1.232 GHz while consuming 765 μW from a supply voltage of 1.2 V.
