In accordance with an embodiment, a method of generating noise includes generating, using a hardware-based noise generator, a plurality of periodic waveforms having different frequencies, weighting, using the hardware-based noise generator, amplitudes of the plurality of periodic waveforms based on a predetermined spectral shape to form a plurality of weighted waveforms, and summing the plurality of plurality of weighted waveforms to form an output random noise signal.

System and method for gaussian random noise generation

A clock and data recovery circuit includes a phase detector circuit, a charge pump circuit, and a voltage controlled oscillator. The phase detector circuit receives a data signal from an external device and a clock signal from the voltage controlled oscillator and generates a first and a second phase difference signal. The charge pump circuit includes an OR gate receiving on its inputs the first and the second phase difference signals and configured to generate a current if the first and/or second phase difference signal is high.
