    • A source driver that responds to image data by generating an output signal which can be used to drive a flat panel display. The source driver includes a gamma decoder and an amplifier. The gamma decoder selects a first voltage among first analog gray voltages based on some upper bits of the image data, selects a second voltage among second analog gray voltages based on other upper bits of the image data, and selectively outputs at least one of the first and second voltages as a plurality of distributed analog signals in response to lower bits of the image data. The amplifier interpolates between the distributed analog signals from the gamma decoder to generate the output signal of the source driver. The amplifier includes bias circuits that are each configured to generate a bias current, and a plurality of MOSFETs. Each of the MOSFETs includes a source, a drain, and a gate terminal. The gate terminal of each of the MOSFETS is separately connected to receive a different one of the distributed analog signals from the gamma decoder. One of the source/drain terminals of each of the MOSFETS is separately connected to a different one of the bias circuits to receive the bias current, and the other one of the source/drain terminals of each of the MOSFETS is connected together at an output node to generate an interpolated signal. The output signal is based on the interpolated signal.
