چکیده
— This paper presents a novel compensation technique for low voltage low power three-stage amplifier driving large capacitive loads. The frequency bandwidth of this amplifier is improved due to usage of dual-active buffers in the efficient compensation network while a feed forward transconductance helps to enhance output large signal response. The paper provides a design procedure by developing the mathematical and analytical insight for the compensation network elements using phase margin as the main design parameter. The circuit level simulation for the proposed amplifier with a 0.35μm standard CMOS process resulted 6.7MHz unity gain bandwidth and 67 degree phase margin while driving 1-nF load from a single 2V power supply
