Abstract
The invention provides a signal-powered integrated circuit (IC). The IC comprises an integrated circuit die including a ground node, a supply node, and a first terminal for receiving a digital data signal having data content and a predetermined energy. A receive buffer formed on the integrated circuit die is connected to the first terminal and capable of receiving the data content associated with the digital data signal. A rectifier is also formed on the integrated circuit die. The rectifier includes a first diode connected between the first terminal and the ground node and a second diode connected between the first terminal and the supply node. The rectifier is configured to rectify the digital data signal and pass at least a portion of the digital data signal's predetermined energy to the supply node. Each of the first and second diodes is capable of withstanding an ESD impulse.
