Latest Patents

One of his latest patents focuses on mitigating gain mismatch interference in analog-to-digital converter circuitry. This invention involves an analog-to-digital converter (ADC) that includes interleaved channels to generate output digital signals from input analog signals. The first channel comprises sub-ADC circuitry, amplitude detection circuitry, and correction circuitry. Random chopping is applied at the input of the sub-ADC circuitry during sampling. The sub-ADC circuitry outputs digital data corresponding to the chopping states. Gain mismatch within the chopping circuitry is addressed by determining correction values through the amplitude detection circuitry and applying these values to the output of the sub-ADC circuitry. The amplitude detection circuitry identifies an amplitude difference between data signals, while the correction circuitry generates and outputs the necessary correction values to adjust the data signals.

Another significant patent involves buffer circuitry with improved bandwidth and return loss. This electronic system includes a buffer and analog-to-digital circuitry. The buffer circuitry receives an input signal and includes coil circuitry with a first and second inductor. Additionally, a resistor and a capacitor are integrated into the buffer circuitry to enhance performance. The buffer circuitry is designed to output an output signal based on the input signal.
