Abstract:
In this paper, we propose a novel approach to
increase the -3 dB Bandwidth of a two stage operational amplifier (opamp) by adding a Voltage Attenuator (VA) in the compensation path. This technique reduces the Miller Effect by a factor
K, which improves the -3 dB point by the same factor. Here, K
is equal to the gain of the attenuator. Results indicate that the
proposed technique achieves -3 dB Bandwidth improvement of
38.6 times over the Miller Compensation technique and 20 times
over the state-of-the-art FFVF Compensation technique.
