Introduction

Pi-Cheng Chen is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of semiconductor technology, particularly in the area of phase-locked loops and chip design verification. With a total of 2 patents, his work has had a considerable impact on electronic systems.

Latest Patents

One of his latest patents is titled "Method and system of characterization and behavioral modeling of a phase-locked loop for fast mixed signal simulation." This invention involves a piecewise linear phase-locked loop frequency generator that generates a voltage signal controlled by an input voltage. The frequency generator features a variable static frequency generator, which is selected by a control voltage. The transfer function between control voltage and output frequency is determined by a piecewise linear determination parameter. This parameter selects which portion of the frequency spectrum is represented by the control voltage to frequency transfer function. The invention also includes a model of a phase-locked loop to be simulated within a simulator to determine its function within an electronic system.

Another significant patent is the "Method for cell modeling and timing verification of chip designs with voltage drop." This method produces a whole chip timing verification that accounts for voltage variation effects on delay. It involves creating a netlist, defining cell input and output delay paths, and calculating timing differences caused by power supply voltage variations. The modified whole chip timing data file is then used with traditional timing verification tools for comprehensive cell-level timing verification.
