Abstract:
The present invention reveals a new biasing method which can be used in solid state audio power amplifier design despite of the Class of operation. The proposed biasing technology relies only on traditional electrical feedback to build up and maintain the desired biasing current and doesn't need thermal coupling or thermal tracking techniques in order to overcome power transistor device's temperature dependent input-output characteristics as required by traditional approach. An ingenious current sensing and amplification circuit is devised in order to generate an voltage output which is only corresponding to the quiescent biasing current of the output stage. This voltage output is then used as an representative of the power stage biasing current to be regulated by a feedback loop comprising a traditional voltage multiplier, the output stage and the aforementioned current sensing and amplification circuit.

Claim (Index 15):
A biasing circuit as recited in  claim 14 , wherein a local feedback resistor is inserted between said input and output node of each single ended amplifier of said voltage multiplier.
