Universal current-mode filters and parasitic impedance effects on the filter performances
(John Wiley & Sons, 2008-03)
In this letter, two universal current-mode (CM) filters for simultaneously realizing low-pass, band-pass and high-pass characteristics are proposed. Both of the presented filters can also realize notch and all-pass responses ...
Signal limitations of the current-mode filters employing current conveyors
It is well known that second-generation current conveyors (CCII) are widely used for the realization of second-order current-mode universal filters. A filter with high-quality factor (Q) and gain constant (K) suffers from ...
