Latest Patents

One of his latest patents is titled "Track and hold with dual pump circuit." This invention features a dual pump circuit that includes a transmission gate and a dual charge pump. The transmission gate consists of a p-channel transistor and an n-channel transistor, each equipped with a control terminal and a pair of current terminals linked between a dual pump input and output. The dual charge pump comprises first and second pump circuits, each connected to the dual pump input and a control terminal of the corresponding transmission gate transistor. This design aims to linearize the operation of the transmission gate transistors by maintaining VGS—VT constant. The dual pump circuit is utilized in a track and hold circuit that includes at least one dual pump sampling circuit, one sampling capacitor, and a control circuit for managing input signal sampling timing.

Another significant patent is the "System and method of DC calibration of amplifiers." This compensation system is designed for calibrating an amplifier with a compensation input. It includes a sigma delta converter, a counter, a memory, adjust logic, a DAC, and a pair of compensation capacitors. The converter transforms an offset voltage into a bit stream, while the counter retains a sum value indicative of the output offset. The memory stores a digital bias value, and the adjust logic determines an adjustment value based on the sum value, modifying the stored digital bias value accordingly. The DAC then converts this digital bias value into a differential bias current, which is applied to the compensation input of the amplifier through the compensation capacitors.
