Differential amplifier

Power stage

Tha system is more stable

Higher output voltage can be reached

The higher the nubber of transistor, the smarter the network

The β parameter of the pair is the multiplicant of the individual ones.

The input offset voltage () is a parameter defining the common mode DC voltage required at the inputs of an amplifier to make the output zero

The input offset voltage () is a parameter defining the differential DC voltage required between the inputs of an amplifier, especially an operational amplifier (op-amp), to make the output equal to the half of the positive power voltage.
