Abstract
A circuit is disclosed. The circuit includes a transmitter having an input terminal arranged to receive input data and a transmission node arranged to transmit intermediate data corresponding to the input data, and a receiver having a receive node arranged to receive the intermediate data and an output terminal arranged to produce output data corresponding to the input data, the receiver further including a dV/dt detector circuit coupled to the receive node and arranged to stop the production of the output data at the output terminal when the dV/dt detector circuit detects a rate of change of voltage with respect to time greater than a predetermined threshold.
Claims20
A circuit comprising:
- a transmitter having an input terminal arranged to receive input data and a transmission node arranged to transmit intermediate data corresponding to the input data;
- and
- a receiver having a receive node arranged to receive the intermediate data and an output terminal arranged to produce output data corresponding to the input data, the receiver further including a dV/dt detector circuit coupled to the receive node and arranged to stop the production of the output data at the output terminal when the dV/dt detector circuit detects a rate of change of voltage with respect to time greater than a predetermined threshold.
A method of operating a circuit, the method comprising:
- providing a transmitter having an input terminal arranged to receive input data and a transmission node arranged to transmit intermediate data corresponding to the input data;
- providing a receiver having a receive node arranged to receive the intermediate data and an output terminal arranged to produce output data corresponding to the input data, the receiver further including a dV/dt detector circuit coupled to the receive node;
- receiving, by the transmitter, the input data;
- transmitting, by the transmitter, the intermediate data corresponding to the input data;
- receiving, by the receiver, the intermediate data;
- and
- producing, by the receiver, the output data corresponding to the input data at the output terminal.
