WebJul 17, 2024 · \$\begingroup\$ Strictly speaking, when the input voltage increases, the output voltage decreases i.e. this type of amplifier is an inverting type. In a good amplifier and ignoring inversion, the gain should remain close to constant. \$\endgroup\$ – WebMar 21, 2024 · 7.6.1: Direct Coupling. With a little creativity, it is possible to create multi-stage designs that use fewer components but which achieve higher performance. One technique is to employ direct coupling of the stages. Direct coupling allows DC to flow from stage to stage. As such, it is possible to design an amplifier that has no lower frequency ...
