Title: Wei Tjan Lim: Innovator in Analog-to-Digital Conversion and Filter Calibration
Introduction
Wei Tjan Lim is a notable inventor based in Fort Collins, CO (US). He has made significant contributions to the field of electronics, particularly in the areas of analog-to-digital converters and continuous-time filters. With a total of 2 patents, his work showcases innovative solutions that enhance measurement and calibration processes.
Latest Patents
Wei Tjan Lim's latest patents include an "Analog-to-digital converter with power supply-based reference." This invention provides a measurement circuit designed to measure the resistance of a variable resistance element that is biased with an external voltage supply. The circuit features an analog-to-digital converter (ADC) that receives a reference voltage and a voltage developed across the variable resistance element, generating a digital output signal indicative of their relationship. The reference generator creates the reference voltage based on the external voltage supply.
Another significant patent is the "Method and system for tuning precision continuous-time filters." This method involves calibrating a continuous-time filter with adjustable parameters. A square-wave signal is filtered, and the resulting signal is quantized. An N-point Fourier transform is performed, leading to the accumulation of real and imaginary output values. The output signals are then compared to a reference value, allowing for adjustments to the filter parameters until the desired output is achieved.
