Latest Patents
One of his latest patents is for a current fault detection system and method for a current sensor. This system includes fault detection circuitry designed to identify over-current and current faults when the current through a conductor exceeds a predetermined level. The current sensor features a shared signal path, a main signal path, and a fault detection signal path, enabling both fault detection and current detection signal processing. Additionally, it incorporates magnetic field sensing elements that generate a magnetic field signal indicative of the current, an analog-to-digital converter (ADC) for converting this signal into a digital format, and a fault detector that generates a fault signal when necessary.
Another significant patent involves a voltage buffer for input voltages that exceed the supply voltage or fall below ground voltage. This buffer amplifier consists of a source follower and a feedback amplifier, which is configured to maintain a constant drain current of the source follower, regardless of the load.
