Fig 4: SPICE simulation of the output stage gain variation with and without a constant 1Amp of
displacement current. The central peak is moved left from 0V to -8V.
Realisation
There are several ways in which a suitable displacement current can be drawn from the main
amplifier output node.
Resistive crossover displacement
The most straightforward way to implement crossover displacement would be to simply connect a
suitable power resistor between the output rail and a supply rail, as shown in Fig 5.
