摘要
In this literature, a gain-boosted folded cascode fully differential amplifier with a common-mode feedback circuit (CMFB) is developed based on the 0.18 µm, 1.8 V CMOS process. Amplifier uses the gain-boosting approach on both NMOS and PMOS branches to enhance the amplifier's total gain. The amplifier achieves 112 dB gain, ~620 MHz bandwidth at the expense of 2 mW power consumption. The amplifier's performance is mostly better than the contemporary ones in terms of FOM, power budget, settling time, and noise.
