A method and an apparatus are described for an offset correction in a high gain amplifier. An embodiment of an amplifier circuit includes an amplifier to convert a current signal into a voltage signal, where the amplifier generates an offset voltage in the voltage signal. The amplifier circuit also includes a sampling component coupled with the amplifier, with the sampling component subtracting a first sample of the voltage signal from a second sample of the voltage signal to produce a difference value. The amplifier circuit further includes a gain component coupled with the sampling component to amplify the difference between the first sample and the second sample.
