Unlike traditional Class AB designs, its bias current does not depend on temperature and no adjustment is required. Diodes D1 and D2 are on when transistors are not conducting so the op-amps are ...

ThermalTrak integrates power output transistors with thermal bias diode. One of the major design concerns in the output section of a typical class AB audio amplifier is output bias and stability over ...

2). Made on a 0.8-µm CMOS process, the X9470 is crafted to set the bias operating points for class A or AB amplifiers. While the drain current is constant in type A, it's always changing in class ...
