WebApr 11, 2024 · This is known as the gain bandwidth product (GBP). Hence, any increase in gain is a dividing factor in the bandwidth. In the case of CFOAs, the cutoff frequency is a function of “1/(2*pi*R2*Cc)”. This means that the cutoff frequency can be chosen with the selection of “R2”, and that for a CFOA, the gain and bandwidth are independent.
