Webb12 juni 2024 · Since the 2nd stage's input impedance (unspecified) will load down the 1st stage's output, thus reducing the signal seen by the 2nd stage, the calculation of the 2nd stage voltage gain is a little more complicated. For example, the output of the 1st stage is around \$8\:\text{V}_\text{PP}\$. WebbTo achieve high linearity and gain, the output stage of a class A amplifier is biased “ON” (conducting) all the time. Then for an amplifier to be classified as “Class A” the zero signal idle current in the output stage must be equal to or greater than the maximum load current (usually a loudspeaker) required to produce the largest output signal.

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. WebbTypical voltage sources range from ±5 V to ±25 V. Figure 12 shows typical power supply connections to the op-amp. The maximum output voltage swing is limited by the dc voltage supplied to the op-amp. Some operational amplifiers can be operated from a single voltage source. philips pasta maker cookies recipe
