Abstract
The active feedback block considered in this correspondence consists of three identical single-pole amplifiers and a resistive network, and has a positive slope in the gain frequency characteristics over a certain frequency range starting from dc. When the device is cascaded to another single-pole amplifier, the bandwidth and the gain-bandwidth product of the overall system are found to be increased compared to those of a cascaded two-stage amplifier.
