Definition of "class A amplifier" |
The simplest type of amplifier, class A amplifier are those in which the output transistors conduct irrespective of the output signal waveform. This type of amplifier is typically associated with high linearity but low efficiency. / (1) an amplifier in which the active device acts as a modulated current source biased midway between saturation and conduction cutoff. In a class A amplifier, as the amplitude of an applied sinusoidal signal is increased, the output will start to clip at both ends simultaneously. This is equivalent to a conduction angle of 360 degrees as long as the output signal is not clipping, which is avoided. This term is often used to include any amplifier operating with signal levels lowenough such that signal clipping is not present (i.e., small signal conditions). |
