Introduction
Xingfa Huang is a notable inventor based in Chongqing, China. He has made significant contributions to the field of electronics, holding a total of seven patents. His work primarily focuses on advanced circuit designs and programmable technologies.
Latest Patents
One of his latest patents is a clock drive circuit. This circuit includes an input stage, a double-ended to single-ended conversion stage, and a driver output stage connected in sequence. The input stage features two mutually loaded differential amplifiers and a common mode negative feedback loop. The differential amplifiers are connected to a differential clock signal for amplification, generating a common mode voltage. The common mode feedback circuit stabilizes the output amplitude of the common mode voltage. The double-ended to single-ended conversion stage transforms a differential sine clock signal into a single-ended square wave clock signal. The driver output stage employs a multi-stage cascaded push-pull phase inverter to enhance the drive capability of the square wave clock signal.
Another significant patent is a one-time programmable capacitive fuse bit. This invention includes an upper plate with multiple fuses arranged side by side, spaced apart by an internal distance. The middle portions of two adjacent fuses are interconnected. A connecting portion is positioned above the two ends and the middle portion of each fuse. The lower plate corresponds to the two ends and the middle portion of the fuse, with a hollow portion situated between the lower plates.
