Latest Patents

One of Dabin Zhang's latest patents is titled "Hybrid asynchronous gray counter with non-gray zone detector for high performance phase-locked loops." This invention describes systems, apparatuses, and methods for implementing a hybrid asynchronous gray counter with a non-gray zone detector. The circuit includes an asynchronous gray counter coupled to control logic, which programs the counter to operate in different modes for various functions associated with a high-performance phase-locked loop (PLL). In the first mode, the counter acts as a frequency detector, counting oscillator cycles within a reference clock cycle. In the second mode, it serves as a coarse phase detector to identify phase errors between a feedback clock and a reference clock. In the third mode, it functions as a multi-modulus divider to create a feedback clock from an oscillator clock. This innovative approach reduces power consumption and area utilization by using a single asynchronous gray counter for three separate functions.

Another significant patent by Zhang is the "Method and apparatus for clock signal distribution." This patent discloses a clock distribution network and method for distributing a clock signal. In one embodiment, the network is coupled to at least a first circuit and includes a clock source that generates a differential clock signal. This signal is transmitted over a differential signal path via a current mode logic (CML) driver, with a CML receiver set to receive the clock signal through the same path.
