Using a two-X and two-Z second-generation current conveyor (TXTZCCII) as an active building block, two new single-element-controlled sinusoidal oscillator circuits are proposed. The circuits use only the minimum passive components, two capacitors and two resistors. All proposed circuits enjoy oscillation control through a single grounded passive element(s) and independent frequency control through...
With the increasing complexity of the circuits it is essential that students work on the experiments which enhance their circuit analysis and design skills. Circuit simulation tools like PSpice and Multisim are extremely useful tools in understanding the operation of the circuits. However undergraduate level simulation experiments are limited to very simple experiments and mostly concentrate upon...
A new electronically tunable current-mode high-Q bandpass filter employing second-generation current controlled conveyor (CCCII)-based first-order all-pass filters is presented. The proposed filter uses only three CCCIIs, one current-controlled resistor and two grounded capacitors. The center frequency (??c) and the quality factor (Q) can be independently adjusted through the bias current of the CCCII...
This paper introduces a novel current-mode biquadratic circuit using only plus type differential voltage current-controlled current conveyors (DVCCCs) and grounded capacitors. The biquadratic circuit is constructed with two plus type dual current output DVCCCs (DO-DVCCCs) and two grounded capacitors. The circuit can realize biquadratic circuit transfer functions by choosing the appropriate input and...
