In this paper, an efficient frequency compensation method is investigated for a four-stage CMOS amplifier. The frequency compensation network includes two sets of capacitors at the differential block output. The proposed compensated amplifier is described symbolically to obtain the transfer function. Meanwhile, the proposed configuration is designed at the circuit level and is simulated via 0.18[Formula: see text][Formula: see text]m CMOS technology. Compared to the other existing methods, the proposed amplifier satisfies the figure of merits considerably. This stems from the fact that lower capacitor values are used to perform compensation, leading to lower die occupation, and reach boosted gain bandwidth products. Leveraging both the configuration and design procedure, a high-performance four-stage is presented in this paper.
