Abstract
An amplifier slew rate boosting scheme for use with an amplifier having a closed-loop gain equal to or very near unity has one plate of a compensation capacitor conventionally coupled to an internal high impedance gain node, but has the other plate of the compensation capacitor unconventionally driven with a buffered version of the input signal. The voltage appearing across the compensation capacitor in response to changes in the input signal is significantly less than that achieved using conventional compensation architectures where the other plate of the compensation capacitor is coupled to an AC ground. Since very little current is required to charge the compensation capacitor, the tail current generated by the input stage can be used instead to charge parasitic capacitances within the amplifier to increase the slew rate.
