US 2011/0260551 A1: Circuit and Method for Generating a Pulse Signal (2015)
Abstract: Embodiments provide a circuit and a method for generating a pulse signal. The circuit includes a generating circuit configured to generate a first pulse signal, a branching circuit coupled to the generating circuit and configured to branch the first pulse signal into a second pulse signal and a third pulse signal, and a reflection element coupled to the branching circuit to reflect the second pulse signal. The circuit further includes a combining circuit, which is coupled to the reflection element and the branching circuit and is configured to combine the reflected second pulse signal and the third pulse signal to generate a fourth pulse signal.
