Abstract
An analog amplifier includes at least one signal path. Each of the at least one signal path extends between an input and an output and includes a load device coupled to the output and a transistor coupled to the input. The analog amplifier further includes a dither current source selectively coupled to one of the at least one signal path. The dither current source is capable of supplying dither current to the load device of the selected signal path directly by bypassing the transistor of the selected signal path.
