Latest Patents
One of Liu's latest patents is the "Squelch circuitry for high speed high frequency operation." This invention features a squelch circuit designed to operate efficiently at high speeds and frequencies. It includes a squelch input unit, a low swing pre-amplifier, and a sampling and decision circuit. The squelch input unit processes both positive and negative signals to generate four pre-processed signals, which are then amplified and oversampled. A logic circuit determines the state of the input signal based on multiple samples.
Another notable patent is the "Background-calibrating pipelined analog-to-digital converter." This invention incorporates a multiplying digital-to-analog converter (MDAC) stage with multiple second capacitances. These capacitances are selectively connected to enhance the performance of the analog-to-digital conversion process. The pipelined ADC utilizes a series of MDAC stages, a multiplier, and a low-pass filter to generate a digital output signal while compensating for DC components.
