Abstract: A pulse width widener includes a delay circuit, a processing circuit, and a latch circuit. The delay circuit generates a first signal by delaying an input signal including a first pulse by a delay time. The processing circuit generates a second signal, and the second signal includes information of a second pulse that is temporally extended from the first pulse when a width of the first pulse is smaller than the delay time, based on the first and second signals. The latch circuit stores the second signal and outputs the second pulse as an output signal.

Abstract: A burst mode optical receiver includes a pre-amplifier configured to convert an optical burst mode signal into a voltage signal, a reference controller configured to determine a reference voltage for the voltage signal in response to a mode signal from a host indicating an interval during which the voltage signal is DC balanced, and a main amplifier configured to restore the voltage signal to a data signal based on the reference voltage. Related methods of operation are also discussed.

Abstract: The embodiments of the invention relate to apparatus and method for reducing electromagnetic interference (EMI) and radio frequency interference (RFI) in computer systems via a chaotic wide band frequency modulation. The chaotic noise modulator, in one embodiment, comprises: a master cell to generate a control voltage corresponding to an un-modulated reference signal; and a slave cell having a chaotic signal generator to generate a random noise signal, the slave cell coupled with the master cell and operable to generate a modulated output signal in response to the control voltage.
