Switching Noise Jitter (SNJ) is the aggregation of variability of noise events in the time-domain on the supply bias of an electronic system, in particular with a voltage regulated supply bias incorporated with closed-loop (feedback) control, for instance, SMPS. SNJ is measurable using real-time spectral … See more In switching-mode power supplies (SMPS), noise present in the control loop circuitry of the supply causes dislocation in up-slope and down-slope timing of the saw-tooth ripple waveform. As a consequence, the ripple waveform … See more Noise in the output of DC-DC converters may be random or periodic fluctuations in output voltage, analytically expressed as peak-to-peak voltage or noise spectral density. Fig. 2 and Fig. 3 demonstrate the typical visual characteristics of the output from a switching … See more • TransSiP Inc See more At present, many modern switching DC-DC converters offer dual-mode operation. At full load, the switching frequency is held constant and the voltage is modulated by varying pulse width (pulse-width modulation or PWM), thereby presenting a fixed frequency to … See more Since SNJ occurs on a random basis, the most effective measurement technique employs a determination of how often it occurs.
