Latest Patents

One of I-Ting Lee's latest patents is a phase frequency detector circuit. This circuit includes an edge detector circuit, multiple phase frequency detector sub-circuits, and a decision circuit. The edge detector circuit is designed to receive a first input signal and a second input signal. The decision circuit detects whether a blind condition exists based on the outputs of the edge detector circuit and the outputs of the phase frequency detector sub-circuits. Depending on the decision circuit's result, a corresponding frequency detector sub-circuit provides signals to determine the phase difference between the two input signals.

Another notable patent is the divider-less phase locked loop (PLL). This invention encompasses various techniques and systems for a divider-less PLL and an associated phase detector. In this design, a pulse phase detector signal, a voltage-controlled oscillator positive differential signal, and a voltage-controlled oscillator negative differential signal are received. The system generates up and down signals for charge pumps based on these inputs, facilitating the adjustment of the zero crossing phase of the signals. This innovation significantly mitigates PLL power consumption.
