Latest Patents

One of his latest patents is related to DAC weight calibration. This method involves a digital-to-analog converter (DAC) that receives a sequence of digital input words and encodes them into control words. Each bit in the control word has a corresponding bit weight, and the DAC generates an analog sample by summing these bits weighted by their respective analog weights. The method also includes a measurement procedure to adjust the analog weights based on the detected DC level at the output of the DAC. Another significant patent is for an analog-to-digital converter (ADC) circuit, which comprises multiple converter circuits and a global input for receiving an input voltage. This ADC circuit is designed to generate a one-bit output signal in response to the input voltage.
