A comprehensive study on gain-boosted regulated cascode operational transconductance amplifiers (OTA) is discussed. These amplifiers are usually good for power optimized high-speed designs. However location of an additional pole-zero pair in the transfer function makes the transient response much slower than expected. A new design is proposed along with the systematic approach which get rid of this pole-zero pair and deliberately puts a pair of complex poles to make the design faster.
