ABSTRACT:
A circuit includes a first driver, a second driver, and a transformer coupled to the first and second driver. In operation, the first driver receives a first signal from a first input port, the second driver receives a time-delayed version of the first signal from a second input port, and the transformer provides provide an output signal to an output port. A method includes receiving a first input signal, receiving a second input signal, and then processing the first input signal and the second input signal. The second input signal is a time-delayed version of the first input signal and the processing of the first input signal and the second input signal generates a half-raised cosine signal.
