CLASS-A AMPLIFIER USE CCDT

摘要

Pat ' Darlington circuit , push-pull power amplifier and integrated them one integrated circuit element ( Application Number 10-2003-0063551 ) of the " constant Darlington circuit '(CCD; Constant Current Darlington) or" constant-current Darlington transistor ' CCDT (Constant Current Darlington Transistor) the manner of using a class A amplifier power amplifier , low power voltage When the operation output signal power for the power amplifier and the CCD circuit or method , and this function is built-in semiconductor element to improve the power efficiency according to the load driving by the other power supply separate from the voltage drop which CCDT.
