Latest Patents

Rui Quan's latest patents include a "Resistor ladder digital-to-analog converter with mismatch correction and method therefor." This digital-to-analog converter (DAC) features a series of resistive elements arranged in a ring configuration. Each connection between adjacent resistive elements forms a node, which is coupled to groups of parallel-connected switches. These switches allow for selective coupling of power supply voltages and output terminals, while a mismatch error shaping technique effectively removes induced errors outside a pass-band.

Another significant patent is the "Phase-domain digitizer." This invention utilizes a phase-domain delta-sigma modulator to determine a demodulated phase error based on a phase-modulated frequency signal. The modulator filters the demodulated phase error and provides a bit stream that represents the average phase value. Control logic within the modulator selects from a set of reference signals, enhancing the accuracy of the phase measurement.
