Think of Q3 and R3 (which together form a simple common-emitter amplifier) as a cheesy op-amp within this op-amp. To the extent that this combination does behave as a reasonable approximation to a high-gain element, the voltage at the Adding an op amp to the passive wave shaping and filter circuits described in AC Theory Module 8 overcomes the problem that the gain of passive circuits is always less than 1, the output is always less than the input.

7.4 In the amplifier circuit shown in fig., if open loop gain and open loop band width of the op amp respectively are 105 and 10 H Z, Calculate the bandwidth of feedback amplifier (in Op Amp Circuits Introduction The circuits in this problem set are popular op amp circuits. Indeed, these circuits are used so often that they have been given names: the inverting and noninverting amplifiers, the summing
