Latest Patents

One of Lianrui Zhang's latest patents is titled "Method and system for testing a settling time for a device-under-test." This patent describes a system and method for testing the settling time of a device-under-test (DUT). The method involves activating the DUT to generate an output signal and mixing this output signal with a reference signal to create a mixed signal. An amplitude threshold is set for the mixed signal, and the settling time of the DUT is determined based on the last time the amplitude of the mixed signal crosses this threshold relative to the DUT's activation.

Another significant patent is "Built in loop back self test in design or on test board for transceivers." This invention outlines a method and system for testing a transceiver communication device operating in a test mode. It involves adjusting a transmitter output signal and providing it as a loop back to a receiver. The adjustment includes shifting the frequency and attenuating the amplitude of the transmitter output signal to match predefined parameters of the receiver input signal. The device's pass or fail status is determined by comparing the transmitted and received data.
