Latest Patents
One of Duane's latest patents is the "Power pin to power pin electro-static discharge (ESD) clamp." This invention features an ESD clamp circuit designed for use between separate power rails. The clamp is based on a wide nMOSFET and employs a symmetrical circuit concerning the two power rails, allowing for the discharge of an ESD surge in both polarities of stress. The design includes a large power rail-to-power rail nMOSFET, which is controlled by the output inverter stage of an ESD detection circuit connected to a respective power supply rail.
Another significant patent is the "Floating well circuit having enhanced latch-up performance." This circuit defines the voltage potential of a floating well formed at least one metal-oxide-semiconductor device. It includes a sense circuit that detects voltage at a node connected to the floating well and generates a control signal indicative of whether the voltage is within a specified range. The circuit also features a voltage generator that produces a bias signal to set the voltage potential of the well in response to the control signal.
