Latest Patents
One of his latest patents is the "MOSFET with temperature sense facility." This invention integrates a Field Effect Transistor (FET) with a temperature sensing diode. The gate drive circuit is designed to switch off the FET, while a biasing circuit drives a constant current through the diode. The voltage across the diode is measured by a voltage sensor, providing a measure of the temperature of the FET.
Another significant patent is the "Circuit and method for determining current in a load." This circuit is designed to determine the current in a load, featuring a main transistor and a sense transistor. Each transistor has a main current path and a control terminal, with the main current paths connected in parallel between the load and a ground terminal. The control terminals are interconnected, and means are provided for setting the voltage across the main current path of the sense transistor to a level substantially equal to a predetermined portion of the voltage across the main current path of the main transistor.
