Abstract
A method for current limiting an operational amplifier includes sensing a first current through a first branch of the operational amplifier. The first branch conducts the first current from a limited current supply connected to an operational amplifier output. The first current is compared to a reference current to generate a regulation signal. A variable current source is controlled with the regulation signal. An output current of a transconductance amplifier is limited with the variable current source to limit the first current in response thereto.
