Abstract :
A general synthesis procedure for the realisation of an nth-order lowpass voltage transfer function by a fully integrated circuit is presented, and a CFA based fully integrated nth-order filter which uses (n) CFA based integrators and only grounded capacitors is given. This circuit is especially suitable for monolithic implementation
