Title: The Innovations of Chan-Hsiang Weng
Introduction
Chan-Hsiang Weng is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of electronics, particularly in the development of advanced input buffers and analog-to-digital converters. With a total of 10 patents to his name, Weng's work has had a substantial impact on the industry.
Latest Patents
One of Weng's latest patents is the "High-linearity input buffer." This invention utilizes a frequency-dependent impedance circuit to compensate for nonlinearity in low frequencies. In a pseudo-differential architecture, the frequency-dependent impedance circuit is coupled between the drain of a positive input transistor and the drain of a negative input transistor of the flipped voltage follower. In a single-ended architecture, it is coupled between the drain of an input transistor and an alternating current ground, incorporating a capacitor for enhanced performance.
Another notable patent is the "Analog-to-digital converter having quantization error duplicate mechanism." This invention features an ADC that includes multiple switched capacitor arrays and an integrator. The first switched capacitor array samples the input signal to generate a first sampled signal, while the second and third arrays generate quantization errors. The integrator processes these errors in a time-interleaving manner, allowing for improved accuracy in the digital output signal.
