ABSTRACT:
A dynamically limited amplifier including an operational amplifier having both non-inverting and inverting input terminals, an output terminal, and dynamic limiting circuitry connected between the inverting input and output terminals of the operational amplifier. The dynamically limiting circuitry operates to supply a feedback current between the output terminal of the operational amplifier and the inverting input terminal of the operational amplifier, whenever the output voltage of the operational amplifier exceeds a threshold potential.
