Title: Zhichao Tan: Innovator in Analog-to-Digital Conversion Technologies
Introduction
Zhichao Tan is a prominent inventor based in Wilmington, MA (US), known for his significant contributions to the field of analog-to-digital conversion. With a total of 5 patents to his name, he has developed innovative technologies that enhance the performance and efficiency of analog-to-digital converters.
Latest Patents
One of his latest patents is focused on noise shaping pipeline analog to digital converters. This patent describes a pipeline ADC architecture that utilizes feedback to implement noise shaping. By feeding back the residue generated by the last residue generating stage to selected locations in the pipeline ADC, the architecture effectively creates a finite impulse response (FIR) filtered version of the quantization error. This results in spectral shaping of the quantization noise, leading to improved performance compared to conventional pipeline ADCs. Another notable patent is a method of performing analog-to-digital conversion using a successive approximation (SAR) ADC. This method involves comparing a previous digital output to a defined range based on the first M bits of that output, allowing for preloading of the digital-to-analog converter (DAC) to enhance accuracy and reduce the likelihood of errors.
