ABSTRACT:
A transimpedance amplifier having open-loop DC control is provided. The open-loop feedback control may provide a DC bias that is configurable based on the characteristics of an input device, such as, a photodiode or a magnetoresistor. The open-loop feedback control may provide quick recovery from voltage level variations and may provide stability for the amplifier.
