Title: The Innovative Contributions of Jay Friedman
Introduction
Jay Friedman is a notable inventor based in Felton, CA (US), recognized for his significant contributions to technology with a total of 10 patents. His work primarily focuses on advancements in thermostat circuits and display technology, showcasing his expertise in electrical engineering and innovation.
Latest Patents
One of Friedman's latest patents is a low voltage thermostat circuit. This innovative thermostat circuit operates effectively with very low supply voltages and does not require a separate constant value as a reference. It features improved temperature sensitivity compared to prior art thermostat circuits. The circuit compares two reference currents, I and I. When I exceeds I, the output of the thermostat circuit changes to one logic state, and when I is greater than I, the output switches to a different logic state. The circuit includes a PTAT current generator and a V current generator, which can be implemented with cascode amplifiers. Additionally, the circuit has a testing and tuning capability that allows for the injection or subtraction of test currents.
Another significant patent is a display column driver with chip-to-chip settling time matching means. This invention addresses the issue of uneven brightness in flat panel field emission display (FED) screens. The device normalizes the settling time of column amplifiers, which can vary due to differences in semiconductor processing. By sensing the output of the column driver and adjusting the amplifier bias voltage, the invention ensures that the settling times of all column drivers are matched, effectively eliminating brightness variation problems.
