Insensitive multifunction filter implemented with current conveyors and only grounded passive elements

The paper presents a new multifunction filter which can simultaneously real ise low-pass, high-pass and band-pass functions. he circuit employs only po sitive-type second generation current conveyors, grounded passive component s and exhibits high input impedance. No element matching conditions are imp osed. The filter permits orthogonal adjustment of quality factor Q and omeg a(0). For one possible set of component selection the filter permits compen sation for the parasitics. The passive sensitivities are shown to be low.
