Title: The Innovations of David James Megaw
Introduction
David James Megaw is a notable inventor based in Tucson, AZ. He has made significant contributions to the field of electronics, holding a total of 10 patents. His work primarily focuses on improving the efficiency and functionality of electronic circuits.
Latest Patents
Among his latest patents is the "Power FET Gate Charge Recovery." This invention presents a circuit designed to recover charge at the gate of an output transistor, which is crucial for driving the output of switching circuits like regulators or controllers. The circuit effectively recovers a substantial portion of the charge during each switching cycle, regardless of the load conditions, whether it be no load, partial load, or full load. Additionally, this charge recovery mechanism operates efficiently in both synchronous and asynchronous switching circuits. Notably, when the output voltage of a switching circuit exceeds 12 volts, the potential charge savings can be significant.
Another important patent is the "Start-Up Circuit for a Shunt Regulator." This method and circuit control the start-up of a shunt regulator using an error amplifier for normal operation. Upon start-up, the circuit clamps the output voltage to a level below the target value, then applies regenerative positive feedback to navigate through potentially adverse conditions. Finally, it releases the positive feedback near the target value, allowing the error amplifier to take over regulation.
