Abstract
A transconductance-enhancement cascode Miller compensation technique is proposed for low supply-power, large or very large capacitive load multistage amplifiers. By using the transconductance-enhancement operational amplifiers and the local impedance attenuation network, both the gain bandwidth and setting time are thus significantly improved. The effectiveness of the method has been verified in a 0.18â¯Î¼m CMOS process, the proposed three-stage amplifier has over 100â¯dB gain, 6.5â¯MHz gain-bandwidth product, and 0.83â¯V/μs slew rate while consuming 23â¯Î¼W power from a 1.2â¯V supply while driving a 560â¯pF load.
