| Abstract: | A circuit realizing second order all-pass and notch filter,
employing current conveyors and operational amplifier/CFA as the active circuit
elements is proposed. The circuit uses only two current conveyors, one
operational amplifier/current feedback amplifier, four resistors and two
grounded capacitors. The current conveyors used in the circuit are replaceable
by translinear current conveyors and thus quality factors Q and center frequency become controllable through the bias
currents of the translinear current conveyors. The filter also displays low
incremental parameter sensitivities. The simulation results on the filter
support theory. |
