In this paper a frequency compensation method for operational transconductance amplifiers is proposed, which poses no power overhead compared to Miller compensation, while improving the 3dB 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.
