Latest Patents

Among her notable innovations are two recent patents for an ADC (Analog-to-Digital Converter) apparatus and control method. The first patent outlines an apparatus featuring a plurality of binary weighted capacitors arranged between a comparator's first input terminal and several signal buses. The capacitors exhibit a binary weight that doubles from the first capacitor to the (N−K)th capacitor, with subsequent capacitors maintaining a constant binary weight. This setup includes an offset voltage generator that produces a digitally controlled offset voltage fed into a comparator's second input terminal. Additionally, a successive approximation logic block receives the comparator's output and generates an N-bit control signal to manage the binary weighted capacitors.

The second patent describes a methodology for converting an analog input signal into a digital output signal. This process involves integrating a digitally controlled offset voltage into the comparison stage of a successive approximation analog-to-digital converter circuit. This control voltage follows a periodic pattern that includes multiple steps, facilitating the generation of multiple N-bit digital signals that are then summed and processed to yield a digital signal with enhanced bit resolution.
