I have 2 inverting op amps connected with a resistor. Eventually I'll be finding the transfer function, but right now I'm just stuck on KCL.
Here's my attempt so far:
0 = i1 + i2 + i_ *since i_ = 0, we have i1 + i2 = 0
i1 = (Vi - VA)/R1
i2 = (V1 - VA)/(R2 in parallel with C1)
What is R2 in parallel with C1?
Then, after I find Vi, it will be the input voltage to the second op amp, correct?
