A current of an internal amplifier stage may be increased or decreased in relation to the increasing or decreasing of the gain to provide adjustments to bandwidth and/or frequency response. In one embodiment a programmable gain amplifier having operational amplifier has a variable feedback resistor ...

The frequency response must extend full audio band 20 Hz to 20 KHz. The tolerance to the frequency response is ±3db. The conventional way of specifying the bandwidth is an amplifier is down by 3db from the nominal 0db. Noise: The power amplifiers should produce low noise when the power am...
The output from the current mirror drives a voltage amplifier and power output stage, which is connected as an integrator. The integrator controls the open-loop frequency response, and its capacitor may be added externally, as in the 101, or self-contained, as in the 741. Most descriptions ...
