Latest Patents
Eric Duvivier holds a patent for a differential amplifier that features a double differential amplifier pair. This invention includes a tunable quadrature phase shifter, which consists of two branches, each made up of a filter, an amplifier, and a summing circuit. The design incorporates cross-connections that link the filter of one branch to the summing circuit of the opposite branch through amplifiers. This configuration allows for an accurate 90-degree phase shift between the two output signals by controlling the tail currents of the four amplifiers. The phase shifter is particularly beneficial for mobile telecommunication transceivers, as it can be easily and accurately tuned. It operates efficiently with a 3 Volt battery supply, which is commonly used in wireless phones. Additionally, the bandwidth of the amplifiers is enhanced by utilizing double differential pair amplifiers that function as cascode arrangements.
