The fast switching capability and zero reverse-recovery charge result in higher output linearity and low crossover distortion
for lower THD.
Class B eliminates the quiescent bias current of Class A and AB but, as a result, introduces crossover distortion
Class B is rarely used in practical applications because of the large crossover distortion
In addition, the amplifier's integrated AQC (adaptive Q-current control) circuit dramatically decreases crossover distortion
even when consuming low quiescent current.
The integrated, adaptive bias current control circuit of the FAN7031 significantly decreases crossover distortion
, even though it consumes low quiescent current.
The device utilizes an integrated adaptive bias current control circuit to minimize crossover distortion
even while consuming 54 percent lower quiescent supply current than other competitive devices.
This is the crossover distortion
which is introduced when the current monitor IC changes from conducting in one direction to conducting in the opposite direction.
This class AB output stage has a zero dead band and minimal crossover distortion
Fast rise and fall times (25ps), less than 5% crossover distortion
with less than 10% overshoot ensure reliable signal recovery.
A new output architecture delivers high output current with minimal headroom and crossover distortion
All three devices are single supply rail-to-rail output operational amplifiers with no crossover distortion
, fully redesigned for 2.
After much study, my colleagues and I concluded the boost-type power converter (Figure 2) best suits the implementation of a PFC circuit because of the absence of crossover distortions
and the viability of operating the converter in continuous-conduction mode.
