摘要：
A novel current-mirror miller compensated two-stage amplifier is presented. The proposed design improves both large-signal performance and small-signal performance of conventional two-stage amplifiers. This design eliminates the low-frequency right half-plane zero and reduces the output parasitic capacitance of the first stage without inducing additional input offset voltage and DC8 gain degradation8 Detailed ansisi performed to justify the proposed design. The design is simulated in UMC130 CMOS technology. Simulations agree well with analysis. This idea may be extended to multistage amplifiers, low-dropout regulators and other applications.
