Three-phase digital-signal generator sweeps frequency

Many power ICs use frequency jitter, which spreads a control signal's spectrum, to control EMI (electromagnetic interference). If you need to add frequency jitter to power ICs that control three-phase ...

Shift Register Generates Multiple Clocks From PWM Signal

This circuit transforms a pulse-width-modulation (PWM) signal into non-overlapping clock signals, whose number depends on the length of a shift register. These clock signals can be used to power up ...
