Title: The Innovations of Patrick G Farrell
Introduction
Patrick G Farrell is a notable inventor based in Baltimore, MD (US). He holds a total of 4 patents that showcase his contributions to the field of technology. His work primarily focuses on advanced electronic circuits and systems.
Latest Patents
One of his latest patents is a clock recovery circuit. This innovative circuit is designed to recover a clock signal from a high data rate data stream. It features a phase interpolator and non-linear digital to analog converters. These components work together to interpolate between the phases produced by a voltage-controlled oscillator. The circuit also includes an up/down detector, a divider, and control logic to determine whether to advance or hinder a currently selected phase. By dividing the clock frequency, the control logic can be effectively designed using CMOS logic circuits.
Another significant patent is the transmit/receive module for planar active apertures. This T/R module incorporates a multilevel, multichip microwave package that contains several gallium arsenide monolithic microwave integrated circuit chips (MMICs). These chips implement RF switching elements, a variable phase shifter, RF amplifiers, and gain trim attenuators, all located on a planar RF assembly. The architecture of the module allows for shared MMIC circuit elements during both transmit and receive operation modes, which reduces the number of MMICs required while maintaining efficiency.
