Two capacitors are always used in the previously reported three-stage amplifiers for large capacitive loads. In this paper, the single Miller capacitor compensation approach is introduced to reduce the area and improve the small signal and large signal performance of the amplifiers.
Pole splitting and single miller compensation capacitor are effectively combined to reduce the total capacitor value, and therefore, the total area of amplifier. In addition, another study introduced a differential amplifier in the path of feedback.
Using a single Miller compensation ca-pacitor in three-stage amplifiers can significantly reduce the total capacitor value, and therefore, the overall area of the amplifiers without influencing their stability. Pole-splitting and feedforward techniques are effectively combined to achieve better small-signal and large-signal performances.
compensation capacitor helps to ensure stability while achieving comparatively large bandwidths. All of the above compensation techniques – use Miller capacitors whose sizes depend on the size of the load capacitor. For larger loads the sizes of the Miller capacitors tend to in-crease.
Single Miller capacitor at the output of a fully differential gain stage realizes a frequency compensation network. The proposed amplifier is simpler than NMC and RNMC and shows excellent robustness against mismatches while uses a small and single Miller capacitor.
output that helps in improving the transient response of the am-plifier . A single Miller compensation capacitor is used to split the first pole and the third pole . The position of the second nondominant pole is dictated by the gain of the second stage, which decides the stability of the amplifier.
