Latest Patents
One of his latest patents is a "Discrete Time Filter Network." This invention features an input signal connection and an output signal connection, comprising a capacitor bank with multiple history capacitors. It includes at least one sampling capacitor that operates at a predetermined cycling rate, allowing for the sharing of electrical charge between selected history capacitors and the sampling capacitor. The design incorporates a switch network with clock-driven switches to facilitate cyclical connections between the sampling and history capacitors.
Another significant patent is the "Quadrature LC Tank Digitally Controlled Ring Oscillator." This oscillator structure consists of multiple stages, each containing a buffer and a series LC tank. By coupling four stages together, it achieves a 360-degree phase shift around a loop. The oscillation frequency matches the resonant frequency of each LC tank, which helps avoid quality factor degradation. The use of class-D amplifiers enhances the efficiency and phase noise performance of the oscillator.
