Gain required = 10,000 on a load of 1kOhm
For the final solution we will need to cascade
amplifiers. Hence the transmission parameters
will prove very useful
Analysis of solution:
-Even with infinite load the maximum gain
is only 6,667
Likely causes:
-R2 is higher than input resistance Ri
-Desired gain is comparable to the maximum
gain, A, of the Op-Amp
Proposed solution:
-Cascade two stages, each with ideal gain of
100. This also lowers R2 to 99kOhm
