Abstract:
Audio amplifiers, particularly those employed with headphones, use snubbers to suppress or snub signals within a particular frequency range. Conventional resistive and resistor-capacitor (RC) type snubbers have a number of drawbacks (i.e., require external components and high power consumption). Here, an active snubber is provided that allows for suppression in a desired frequency range without the need for external components and with relatively small footprint and a relatively small power increase.
