Latest Patents
Chi Yun Wang's latest patents include a SAR ADC and method thereof. This innovative SAR ADC comprises a comparator, an input switch unit, a positive conversion capacitor array, a negative conversion capacitor array, and a SAR controller. The input switch unit alternately couples and decouples a differential analog input signal to the comparator. The positive and negative conversion capacitor arrays sample the differential analog input signal during the sampling phase. The SAR controller resets the switches in the capacitor arrays at the end of the sampling phase to change the sampled voltage into a residual signal. It generates an intermediate digital code to control the switches during the conversion phase according to the output of the comparator, converting the residual signal to the intermediate digital code. Finally, it generates the digital code according to the intermediate digital code and uses an inverted intermediate digital code to control the switches at the end of the conversion phase.
Another significant patent is the multi-mode OPAMP-based circuit. This circuit features an input amplifying stage that amplifies a pair of input differential signals to provide a pair of intermediate differential signals. An output amplifying stage further amplifies these intermediate signals to produce a pair of output differential signals. The circuit includes multiple capacitors strategically placed in feedback loops to enhance performance based on control signals.
