Title: Juei-Lung Chen: Innovator in Digital Circuitry

Introduction

Juei-Lung Chen is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of digital circuitry, holding a total of 6 patents. His innovative work focuses on enhancing the efficiency and performance of electronic systems.

Latest Patents

One of his latest patents is the "Digital Delay Phase Locked Loop." This invention is designed to quickly perform phase locking on an input clock signal. The digital delay phase locked circuit includes a delay apparatus, a buffer, a phase comparator, an adder-register, a clock divider, and a demultiplexer. After the delay operation on the input clock signal, the phase locked clock signal is output via the buffer. The phase comparator then compares the two signals, outputting a comparison signal to the adder-register for addition or subtraction delay. The clock divider controls this process, achieving fast phase lock through the operations of the demultiplexer.

Another notable patent is the "Selective Memory Refresh Circuit and Method." This invention pertains to refreshing a memory cell array. The memory cell array consists of multiple word lines connected to word line selection circuits that determine if a particular word line requires refreshing during a refresh cycle. Each word line refresh selection circuit includes a word line address latching device that receives various signals and outputs a word line latching signal. A word line refresh compare circuit then processes these signals to determine if memory cells attached to the word line should be refreshed.
