Calculate the CMRR of this circuit
In the next circuit $$V_{o}=10V_{i}$$,and $$A_{CM}=100$$ how can be calculated the CMRR?
Using the CMRR = 20*log(Adm/Acm), it needs the \$Adm\$, gain in ...

What’s the transfer function of this opamp arrangement?
I never got this one right using superposition. I want to learn from my mistakes. The idea is to get the transfer function based on the coefficients given.
Begin at $$V_i$$ and labeled $$V_a$$, and ...
