Title: Innovations of Didem Z Turker Melek

Introduction

Didem Z Turker Melek is a prominent inventor based in San Jose, CA (US). She has made significant contributions to the field of technology, particularly in the area of clock and data recovery circuits for transceivers. With a total of 11 patents to her name, her work has been instrumental in advancing communication standards.

Latest Patents

One of her latest patents is titled "Flexible wide-range and high bandwidth auxiliary clock and data recovery (CDR) circuit for transceivers." This invention relates to implementing an analog auxiliary clock and data recovery path to provide a high bandwidth CDR in a transceiver that supports both PAM4 and NRZ signaling. The auxiliary CDR path includes a phase-frequency detector (PFD)-based phase-locked loop (PLL) and a phase detector (PD)-based PLL. When the PFD-based PLL is locked to a reference clock signal of the transceiver, it can be disabled while the PD-based PLL is enabled. This implementation allows the transceiver to support new standards such as Peripheral Component Interconnect Express (PCIe) 5.0 and PCIe 6.0.

Another notable patent is the "Method and apparatus for a phase locked loop circuit." This PLL circuit includes a voltage controlled oscillator (VCO), a first loop circuit, and a second loop circuit. The first loop circuit features a loop filter that receives a feedback signal from the VCO, providing a frequency control signal to the VCO. The second loop circuit includes a compensation circuit that receives a reference signal and the first signal, also providing a frequency control signal to the VCO.
