Abstract
A very simple, very inexpensive circuit is described for conditioning a high-voltage source to reduce supply ripple and noise from several volts p-p to microvolts, achieving a wideband supply noise level of better than -140 dB. The noise suppressor achieves its performance by taking advantage of the special nature of the problem-a few volts of ripple riding a large constant background. The device can be retrofitted to an existing supply with an immediate improvement in performance
