Latest Patents

One of his latest patents is titled "Adaptive analog equalization in ADC-based receiver." This invention describes an analog-to-digital converter-based serial receiver that is configured to tune analog equalization settings for link training. The receiver receives an analog signal from a transmitter and applies initial analog equalization settings. It then converts the equalized analog signal into a digital signal. The receiver measures the frequency content of the analog signal and saturation at the analog-to-digital converter, determining updated analog equalization settings.

Another notable patent is "ADC-based SerDes with sub-sampled ADC for eye monitoring." This invention includes digital serializer/deserializer circuitry that features a data path and a data eye monitoring path. The data path consists of a first analog-to-digital converter (ADC) that samples incoming data at a first rate, along with first digital filter circuitry to filter the output of the first ADC. A data slicer is coupled to the output of the first digital filter circuitry to output data above a threshold. The monitoring path includes a second ADC that samples the incoming data at a second rate lower than the first rate, taking samples at varying points along the incoming data waveform. It also features second digital filter circuitry and another data slicer to output data above an adjustable threshold, sweeping through varying threshold values. Error rate circuitry compares the outputs of the data slicers to determine a data eye error rate.
