Abstract:
1. A signal-powered integrated circuit, comprising: an integrated circuit die including a ground node, a supply node configured to provide a supply voltage to a plurality of circuits on the integrated circuit die, and a first terminal for receiving an input signal having data content and a predetermined energy; a receive buffer formed on the integrated circuit die, connected to the first terminal and capable of receiving the data content associated with the input signal, the receive buffer having an output terminal configured to output the buffered input signal; a rectifier formed on the integrated circuit die, the rectifier including a transmit buffer having an input terminal and an output terminal that is connected to the first terminal of the integrated circuit die; and a feedback path connected between the output terminal of the receive buffer and the input terminal of the transmit buffer, and configured such that the buffered input signal passes through the feedback path to the input terminal of the transmit buffer; wherein:
