Title: Yi-Chang Shih: Innovator in Signal Processing Technologies

Introduction

Yi-Chang Shih is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of signal processing, holding a total of 12 patents. His work focuses on enhancing the efficiency and functionality of communication systems.

Latest Patents

One of Yi-Chang Shih's latest patents is a signal receiving circuit and calibration method. This invention includes a radio frequency (RF) front-end circuit, a filter circuit, an amplifier circuit, an analog-to-digital converter (ADC), a compensation circuit, an adder circuit, and a control circuit. The RF front-end circuit down-converts the input signal to generate a down-converted signal. The filter circuit then filters this down-converted signal to produce a filtered signal. The amplifier circuit amplifies the filtered signal based on a control signal, generating an amplified signal. The ADC converts this amplified signal into a first digital code. The compensation circuit generates a compensation code based on the control signal and the gain. The adder circuit combines the compensation code and the first digital code to produce a second digital code, while the control circuit generates the control signal based on this second digital code.

Another notable patent is the transceiver circuit and control method of a frequency synthesizer. This invention features a transmitter circuit, a frequency synthesizer, and a control circuit. The transmitter circuit generates a transmission signal that is transmitted through an antenna. The frequency synthesizer produces a clock signal for the transmitter circuit. The control circuit generates a first control signal to manage the frequency synthesizer's loop bandwidth. When the transceiver circuit is in standby mode, the control circuit sets a first loop bandwidth. After switching to transmission mode, the control circuit adjusts the loop bandwidth to a second value.
