- Homework Statement
- The amplifier of FIGURE 1 has a closed loop gain of 20 dB and R1 =
10 kΩ. The resistors have a tolerance of 5%.
Estimate the output offset voltage of the circuit of FIGURE 1 when
the op-amp used is
i) op-amp A of TABLE A
ii) op-amp B of TABLE A.
- Relevant Equations
- See attached
I’ve been given the attached question and equation in regard to output offset. I know all the required values apart from Rf. Normally id assume Rf was the feedback resistor however that (as far as I can tell from the circuit) is marked as R2. Would I be right if I assumed this value was Rf = r1ǁr2? Any help would be appreciated.
