O. Cicekoglu et al., Insensitive multifunction filter implemented with current conveyors and only grounded passive elements, FREQUENZ, 53(7-8), 1999, pp. 158-160
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.
