Title: Class A audio amplifier with current sink controlled by feedback in dependence on speaker current
Inventor: READ CLIVE WILLIAM WARDER
IPC: H03F1/02
Filed: 1998-02-27
Abstract: An output stage for a power amplifier comprises an amplifying device T1 connected in series with a variable current sink T2 between positive and negative supply rails +/-V. A loudspeaker S is connected between the zero volt rail OV and a point intermediate the amplifying device T1 and the variable current sink T2. A feedback loop A1,A2 is provided for increasing the amount of current required by the variable current sink T2 as the amount of current delivered to the loudspeaker s by the amplifying device T1 falls. Thus, in one half cycle of the input signal Vin, the loudspeaker S is provided with current through the amplifying device T1 and in the other half cycle the variable current sink T2 draws current through the loudspeaker S. When no input is applied, the variable current sink T2 draws a low current and thus the output stage has an improved efficiency compared with conventional class A amplifiers. The voltage across the loudspeaker S is always controlled by the amplifying device T1 and thus cross over distortion will not occur.
