A rectifier input capacitor's size is often considered nebulous. Therefore, common practice is to pick a large size, and if the ripple voltage is low enough, all is okay (see the figure, a). If not, ...
Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...
You have an integrated 16 bit differential 5V ADC in your microcontroller. The input resistance of each ADC input is 3K ohms and the input capacitance is 8 pF. How would you calculate the ADC settling ...
