Latest Patents

Simmons holds a patent for a "Radio frequency integrated circuit for loopback self-test." This invention involves a loop-back self-test circuit that integrates various components on a common integrated circuit chip. The design allows for the transmit signal and a local oscillator (LO) signal to be applied to a mixer, converting the frequency of the transmit signal to that of a receive signal. A voltage-controlled oscillator (VCO) generates the LO signal, while a phase-locked loop (PLL) synchronizes the VCO signal with a reference signal. The circuit's efficiency is further enhanced by a charge pump and a tank circuit, ensuring optimal performance in cellular communication.
