Abstract
A fully differential amplifier slew rate boosting scheme for use with an amplifier having a closed-loop gain very near unity or less has the first plates of the compensation capacitors and conventionally coupled to internal high impedance gain nodes and , but has the other plates of the compensation capacitors and unconventionally driven with the input signal IN+ and IN−. The voltages appearing across the compensation capacitors and in response to changes in the input signal is significantly less than that achieved using conventional compensation architectures where the other plates of the compensation capacitors are coupled to ground. Since little current is now required to charge the compensation capacitors and , the input stage tail current no longer limits the slew rate.
