A simple yet very effective slew rate enhancement (SRE) method is proposed. The proposed SRE feedback is normally off and is activated only when an excessive transient signal in the output stage indicates the onset of slewing. Therefore, the method does not degrade the small signal performances or the linearity of amplifiers as do most existing SRE techniques. The new SRE applies to both single‐stage and multi‐stage, both single‐ended and fully differential amplifiers. Simulation results of an example implementation show more than 700% slew rate boost with less than 2.5% power consumption overhead.
