A voltage amplifier (not necessarily an op amp) has a gain of 100 V/V when its output is left open-circuited. However, when the amplifier’s output is loaded with 1.0 kΩ, the gain is only 85 V/V. The same voltage amplifier has an input impedance of 10 kΩ. If the amplifier’s output is left open-circuited but the source driving the amplifier has a Th´evenin resistance (that is, a source impedance) of 150 Ω, then the gain will be less than 100...

Block-diagram-level amplifier design. In a certain application, an amplifier is needed to sense the open-circuit voltage of a source and force current to flow through a load. The source resistance and load resistance are variable. The current delivered to the load is to be nearly independent of both the source resistance and load resistance. What type of ideal amplifier is needed? If the source resistance varies from 1 k omega to 2k omega and this causes a 1% decrease in...
