Latest Patents

One of Hsin-Shu Chen's 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. These terminals are coupled between a dual pump input and a dual pump output. The dual charge pump comprises first and second pump circuits, which are connected to the dual pump input and to the control terminal of the corresponding transmission gate transistors. Each pump circuit operates to linearize the performance of its respective transmission gate transistor by maintaining VGS—VT constant. This 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 by Chen is the "System and method of DC calibration of amplifiers." This invention presents a compensation system designed for calibrating an amplifier with a compensation input. It includes a sigma delta converter, a counter, a memory, adjust logic, a DAC, a pair of compensation capacitors, and a pair of current to voltage (I/V) converters. 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. The I/V converters charge these capacitors using the differential bias current.
