ABSTRACT:
A multi-reference voltage generator includes an interface controller, a first bank of N m-bit registers and a second bank of N m-bit registers. A first multiplexer has inputs connected to outputs of the first and second bank of registers. An m-bit digital-to-analog (DAC) has an m-bit parallel input connected to an output of the first multiplexer. An analog demultiplexer has an input connected to an analog output of the m-bit DAC. Each voltage storage device in a first group of N voltage storage devices is connected to a corresponding output of the analog demultiplexer. Similarly, each voltage storage device in a second group of N voltage storage devices is connected to a corresponding output of the analog demultiplexer. N further multiplexers each have a first input connected to an output of a corresponding one of the voltage storage devices in the first group and a second input connected to an output of a corresponding one of the voltage storage devices in the second group. N output buffers, each have an input connected to an output of a corresponding one of the N further multiplexers, and an output useful for driving a column driver.
