CB-CC Current-sample current-sum Rf1 = 200ohm Rf2 = 400ohm Rleq = 500ohm Rg = 50ohm B = Rf1/(Rf1 + Rf2) Afi ~= 1/B = 3A/A Avo = Vo/Vg = (Io*Rleq)/Ig*(Rg + Ri) ~= (Rleq/Rg)*Afi = 30V/V Vi = 50mV Vo ~= Vi*Avo = 1.5V ***Adjust the 400ohm resistor in parallel with the 1uF capacitor to change the gain***
