WebbThe total voltage gain can be calculated in either of two ways. First way: the gain of the first stage is calculated including the loading of the R 3 ,R 4 resistor divider. Then the second-stage gain is calculated from the collector of Q 1 which is the output of the first stage. Webb22 maj 2024 · It is necessary to have stages with high voltage gain, high transresistance (ratio of incremental output voltage to incremental input current), or both included in an operational-amplifier circuit. Note that there is no restriction on the number of transistors used in the stage.

WebbThe amplifier stages, however, cannot just simply be connected because the output of a stage is usually characterized by a large DC voltage and a smaller, superimposed AC voltage. Connecting the output of a stage directly to the input of the next stage, the large DC level could easily saturate that stage and make it inoperative.
