Abstract
A circuit for providing a symmetrical output signal to a communication system. The circuit includes an input circuit ( and ) for receiving an input signal and a symmetry circuits ( and ) advantageously configured to provide an output signal exhibiting a symmetrical rising and falling edge waveform in response to the received input signal. An integrated power source (I ) provides current to a common node (N ) in which current is advantageously steered to each half circuit ( and ) to reduce voltage variation on the common node during voltage transition of the input signal, hence, reducing current fluctuation from the current source.
