Latest Patents

Among his latest patents is the "Pipelined ADC having error correction." This invention involves a stage of a pipelined analog-to-digital converter that includes first and second pluralities of digital-to-analog converters (DACs). The first plurality is sufficient in number to produce a residue from the stage, while the second plurality has their outputs added into an analog output of the stage. A mapping circuit can exchange inputs between selected ones of the first and second pluralities of DACs. Additionally, a calibration circuit provides first and second calibration signals to the selected one of the first plurality and another of the second plurality of DACs. These calibration signals correlate to each other but are uncorrelated to an analog input and digital output of the stage, having unequal and partially offsetting effects on the stage's residue. A correction circuit can then correct the digital output of the stage for circuit path errors based on a correlation between the calibration signals and an output of a succeeding stage.

Another notable patent is the "Pipelined analog-to-digital converter." This invention features a plurality of sequentially cascaded stages, each including an amplifier and four copies of a circuit block that includes a flash and capacitors. The four copies of the circuit block operate interleavingly in respective sample, pre-gain, gain, and reset modes. The copies in the sample, pre-gain, and reset modes are decoupled from the amplifier, while the copy in the gain mode is coupled to the amplifier to produce an output for the next following stage.
