Abstract
A system for suppressing transient noise in switched-mode amplifier systems is disclosed. An amplifier, for amplifying a signal from a digital signal source includes a first complementary metal oxide semiconductor field effect transistor (MOSFET) pair. A common node of the pair is serially coupled to an output node of the amplifier by a resistor. The first MOSFET pair is configured to drive a ramp on the output node of the amplifier.
