Abstract:
In this article, a technique has been proposed to extend the common-mode rejection ratio (CMRR) bandwidth of a CMOS differential amplifier. This technique is based on a pole-zero cancellation technique to cancel the dominate pole in the CMRR Transfer function. The differential amplifier tail node swing has been derived under component mismatch conditions, and formulated design methodology for better CMRR. The Circuit has been implemented in 45nm CMOS technology, and simulation results shows CMRR of 114dB at low frequency and 3-dB bandwidth of 30KHz has been achieved, which is approximately 3 times better than conventional technique.
