  • Publication number: 20070146187
    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 sample-and-hold circuit in a first group of N sample-and-hold (S/H) circuits is connected to a corresponding output of the analog demultiplexer. Similarly, each S/H circuit in a second group of N S/H circuits 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 S/H circuits in the first group and a second input connected to an output of a corresponding one of the S/H circuits in the second group.
