Title: Innovations of Anthony Gerard Russell
Introduction
Anthony Gerard Russell is a notable inventor based in San Jose, California. He holds a total of 11 patents, showcasing his significant contributions to the field of electronics and circuit design. His work primarily focuses on developing innovative solutions that enhance the safety and efficiency of electronic devices.
Latest Patents
One of his latest patents is an electronic protection circuit with instability prevention. This protection integrated circuit (IC) safeguards an external load connected to mains supply lines from hazardous conditions such as overvoltage, undervoltage, and overcurrent. The IC features a range detector, a zero-crossing detector, a control unit, a switch driver, and a dummy digital-to-analog converter (DAC). The range detector identifies unwanted conditions, and the control unit disconnects the load upon detecting a zero crossing. A lockout timer ensures a minimum wait time before reconnecting the load, while hysteresis in the window thresholds prevents noise-induced instabilities. The dummy DAC regulates a dummy current to linearize the IC's current consumption around switching points, mitigating instabilities caused by positive feedback during non-linear transitions.
Another significant patent is a circuit having sample and hold feedback control and method. This drive circuit maintains the operating state of the circuit by utilizing a capacitor connected to an inverting input terminal of an operational amplifier and to a terminal of a current-sensitive load through a switch. The operational amplifier's output connects to a switching regulator, which in turn connects to another terminal of the current-sensitive load. An energy storage element is linked to the inverting input terminal of the operational amplifier, storing energy during the first portion of a PWM pulse. This energy is then used to generate an error signal during the second portion of the PWM pulse, ultimately producing a drive signal that biases the current source.
