Abstract
A data transmission system includes a first circuit, a second circuit, and a reference voltage generation circuit. The first circuit includes a transmitter powered by a first power supply voltage and having an input for receiving a data output signal, and an output. The second circuit includes a receiver powered by a second power supply voltage and having a first input coupled to the output of the transmitter, a second input for receiving a reference voltage, and an output for providing a data input signal. The reference voltage generation circuit forms the reference voltage by mixing a first signal generated by the first circuit based on the first power supply voltage and a second signal generated by the second circuit based on the second power supply voltage.
