Latest Patents

Yeh's latest patents include an advanced analog digital converter (ADC) and a method for detecting jitter in clock signals. The analog digital converter features a sample-hold circuit that samples an input voltage, generating a sample-hold output signal. It also includes a digital-to-analog converter (DAC) that produces a DAC output signal, along with a comparator that compares the DAC output with the sample-hold output. This system generates a comparison output signal, which is processed by a SAR combinational digital circuit group and a multiplexer circuit. The multiplexer selects among various output signals for the DAC, ensuring precise control over the capacitor coupling relationship.

The second patent focuses on a method of detecting jitter in clock signals using a phase-locked loop and a jitter detection circuit. This method involves generating lead and lag control signals based on reference and feedback clocks. The jitter detection circuit identifies jitters in the clock signal and outputs a jitter indication signal based on the number of jitters detected.
