Latest Patents: Weimin Zhang holds a patent for "Current-matching intermodulation suppression." This invention provides a circuit designed to suppress second-order intermodulation in a double-balanced mixer circuit. The circuit features a duplicate transconductor element that duplicates AC current in a transconductor pair of the mixer. Additionally, a fundamental cancellation element is included to cancel a fundamental component of the AC current while preserving the second-order intermodulation component. A phase inversion element then feeds the output current of the fundamental cancellation element back to the transconductor pair, effectively removing the second-order intermodulation component from the differential output.
