Introduction

Size, output flexibility and efficiency advantages have made switching regulators common in electronic apparatus. The continued emphasis on these attributes has resulted in circuitry with 95% efficiency that requires minimal board area. Although these advantages are welcome, they necessitate compromising other parameters.

Switching regulator “noise”

Something commonly referred to as “noise” is a primary concern. The switched mode power delivery that permits the aforementioned advantages also creates wideband harmonic energy. This undesirable energy appears as radiated and conducted components commonly labeled as “noise.” ...
