On the optimum design of gain-boosting amplifier for high-speed and low-voltage applications

Currently, there are no studies investigating the issue of speed optimization of gain-boosted cascode amplifier in low voltage applications. This is mainly because of the complicated transfer function of high-swing gain-boosted cascode amplifier structures. This paper proposes a novel and generic model for this amplifier and presents a thorough analysis of its behavior. The aim of this optimization is to eliminate the well-known slow timing component in the step response and obtain the minimum achievable settling time. An ultra high-speed amplifier is presented finally.
