Latest Patents

Denis Crespo holds a patent for a voltage surge protection circuit. This protection circuit is designed to safeguard an integrated circuit with a first supply rail (Vcc) and a second supply rail (Vss) from exposure to excessive voltage. The circuit includes a sensor that detects voltage increases on the first supply rail (Vcc), which can be implemented as an RC element. The sensor's output is connected to a signal path that provides a detection signal. In response to this signal, a clamping circuit is triggered to clamp the first supply rail (Vcc) to the second supply rail (Vss), effectively protecting the circuit during an ESD event. Additionally, a pre-amplifying stage amplifies the detection signal for the clamping circuit, while a hold circuit maintains the control input of the pre-amplifying stage in an enabled state after the detection signal ends. This design enhances the efficiency of the protection circuit.
