A Compensation Technique for Two-Stage Differential OTAs
TLDR
A frequency compensation method for operational transconductance amplifiers is proposed, which poses no power overhead compared to Miller compensation, while improving the 3-dB bandwidth, the unity gain frequency, and the slew rate.Abstract:
In this brief, a frequency compensation method for operational transconductance amplifiers is proposed, which poses no power overhead compared to Miller compensation, while improving the 3-dB bandwidth, the unity gain frequency, and the slew rate. The technique employees positive feedback to introduce an extra left half plane zero to cancel a pole. The phase margin shows good robustness against process and temperature variations. The proposed technique poses no design constraints on the transconductance or capacitor values, which makes it attractive for low-power applications with low area overhead.read more

A 28.8-MHz 23-dBm-IIP3 3.2-mW Sallen-Key Fourth-Order Filter With Out-of-Band Zeros Cancellation
TL;DR: The out-of-band zeros typically present in SK implementations are hereby completely canceled by using a low-power auxiliary path, which leads to a significant improvement of the stop-band rejection, at the cost of a small power for the same auxiliary path biasing.
