Title: Innovations of Lakshminarasimha C Upadhyayula
Introduction
Lakshminarasimha C Upadhyayula is a prominent inventor based in East Windsor, NJ (US). He holds a total of 10 patents that showcase his contributions to the field of electronics and engineering. His work primarily focuses on enhancing the performance and efficiency of electronic components.
Latest Patents
One of his latest patents is the CFET inverter having equal output signal rise and fall times. This circuit comprises P-channel and N-channel field effect transistors, with a conduction electrode of one transistor coupled to that of the other. The design ensures that the currents in the transistors, when changing state, result in substantially equal rise and fall times of the output signal. This is achieved by adjusting the channel length of the P-channel transistor to be smaller than that of the N-channel device, or by modifying the doping level or width of the P-channel device.
Another significant patent is the active element microwave phase shifter. This invention includes a continuously variable phase shifter for a phase range from 0 degrees to 90 degrees, as well as switchable phase shifters. The phase shifters utilize dual gate FET devices to provide the necessary phase shift in a compact structure while maintaining sufficient gain to prevent signal losses. The transmission phase shift is controlled by the DC bias on the second gate and the type of reactive termination applied.
