Well, I'm new in this area, I don't think I got your answer...I have some values however: VCC=10V ,VCM=1.5V, R1=15kΩ, Vg is a sine wave with a frequency of 1 kHz, whose amplitude will be chosen so as to ensure minimal distortion of the output signal (i.e. v0 should also be a sine wave); I need to choose a value for R2 and Cinf in order to have a (theoretical)gain value Av=1500, how can I do this?? I'm new in this area and I would like some formulas and tips how can I solve this
