Patent abstract
DC offsets in high-gain amplifiers should be corrected to avoid the signal distortion that would result from amplifier saturation. A predominantly digital technique is described in which a digital algorithm observes patterns in the sign of the amplifier output and drives a digital-to-analog converter (DAC), which reduces the amplifier's offset.
