Latest Patents

One of his latest innovations is an analog-to-digital converter with an internal timer. This device includes circuitry for receiving an analog input and converting it to a digital signal. It features non-transitory control circuitry that is configured to receive a sampling time and a conversion time. The circuitry also determines a power-up time from at least one sleep mode and causes the digital-to-analog converter to enter into the sleep mode if the sum of the power-up time and conversion time is less than the sampling time.

Another significant patent is a method and apparatus for dithering in multi-bit sigma-delta digital-to-analog converters. This multi-bit Sigma-Delta digital-to-analog converter (DAC) includes a variable resolution multi-bit quantizer. The quantizer has digital value inputs that are truncated or rounded to a resolution that follows a random or pseudo-random sequence. This provides automatic dynamic dithering to remove undesired idle tones in the analog output of the Sigma-Delta DAC.
