Title: The Innovations of Donghai Wang

Introduction

Donghai Wang is a notable inventor based in San Diego, California. He has made significant contributions to the field of technology, particularly in the area of crosspoint switches. His innovative work has led to the development of a unique patent that enhances signal routing capabilities.

Latest Patents

Donghai Wang holds a patent for an NxM crosspoint switch with band translation. This invention allows a signal from any one of the N inputs to be routed to one or more of the M crosspoint switch outputs. The switches within the crosspoint switch can be configured as either voltage mode or current mode switches. In voltage mode switching, an input to the crosspoint switch is provided to an input device, such as an amplifier, which has a low output impedance. The output of this low impedance device is then connected to a switch that links it to a high input impedance device, such as a band translation device. In current mode switching, the low impedance output of the input device connects to selectively activated high isolation transconductance devices with high input impedances. The outputs of these transconductance devices are connected to low impedance devices that function as summing nodes.
