Latest Patents

One of his latest patents is titled "Optimization for an IQ Modulator." This invention focuses on optimizing the performance of an IQ modulator by determining suitable control parameters through the application of known DC biases as the I and Q inputs. The patent outlines how the relative amplitude and actual phase of the sine and cosine carriers can be modulated before they are summed. By measuring an RMS voltage a specific number of times for a related combination of the applied DC biases, Zhou demonstrates that various behavior parameters indicative of mixer performance can be discovered through analysis. These parameters can be assigned a Figure Of Merit (FOM), which indicates how closely the mixer operation approaches ideal behavior. The control parameters can be adjusted over a selected range, and the extraction of behavior parameters can be repeated to find the optimum operating point for the mixer.

Another significant patent is "Compilation of Calibration Information for Plural Testflows." In this invention, Zhou describes a method for obtaining a selection of plural testflows that specify how automated test equipment (ATE) should test at least one device. He identifies calibration information for each testflow and eliminates redundancies to compile a set of non-redundant information for focused calibration over the ATE and selected testflows.
