Popis: A slew-rate enhancement circuit for improving the nonsymmetric slew rate of the output stages is introduced. A signal-dependent dynamic biasing circuit is incorporated to only activate the slew rate enhancement circuit in large signal transients. This circuit is incorporated in the output stage of a folded-cascode opamp design fabricated in a 2 micron CMOS technology. Experimental results demonstrate the desired operation of the proposed circuit. >
