ABSTRACT:
A two-stage, operational transconductance amplifier is provided with a rail-to-rail output swing, zero systematic offset voltage and very low quiescent current, but with the ability to both source and sink substantially greater than the output stage quiescent current to a load during transients. The amplifier has found particular application as part of a switched capacitor gain and filtering block in an implantable defibrillator, but is widely applicable.
