New voltage and current-mode APS using current controlled conveyor

A first-order all-pass section (APS) is introduced employing a single second-generation current conveyor and three passive components. The translinear conveyor version of the circuit employing only two passive components is also proposed. A fully tunable version of the circuit employing two current controlled conveyors (CCCIIs) and a single capacitor is finally derived. All the three versions of APS can be operated both in voltage as well as current mode without changing the circuit configuration. As an application, a quadrature oscillator providing two quadrature currents and two phase-shifted voltage outputs simultaneously, is realized using the proposed APS. RSPICE simulation results for the translinear-C APS, and the translinear-C quadrature oscillator are included to verify the theory.

Novel current-mode all-pass phase shifter using a current conveyor

Using a single second-generation current conveyor (CC II), a current-mode second-order all-pass phase shifter network is proposed. The novelties of the network are the availability of high output impedance, the use of grounded capacitors, and the insensitivity of phase shift relative to the CC II device nonideality. >

New configuration for single-CCII first-order and biquadratic current-mode filters

A new circuit configuration for the current-mode first-order and biquadratic filters using a single second-generation current conveyor (CCII) are suggested. The roposed current-mode single-CCII filters can be easily cascaded without matching circuits. This circuit configuration can be used to synthesize lowpass, bandpass, and highpass functions. The active and assive sensitivities of the roposed filters have been calculated. The quality factor Q and the central frequency ω0 of the roposed filters are insensitive to the current tracking error of the CCII. Five filters are experimentally implemented to verify the theoretical rediction

Universal active current filters using single second-generation current conveyor

Two novel universal active current filters, one of which has multiple outputs and the other of which has a single output and high output impedance, employing a single negative second-generation current conveyor, three position-fixed capacitors and four/five position-fixed resistors are proposed. The proposed networks with the advantages of low passive sensitivities can obtain second-order lowpass, bandpass, highpass, notch and allpass current signals by adjusting the magnitudes of a grounded resistor and a grounded capacitor provided that another resistor is separable. The resonance angular frequency and quality factor are insensitive to the current tracking error of the nonideal CCII–.

The single CCII biquads with high-input impedance

Two new configurations for the design of single second-generation current conveyor (CCII) biquad (SCB) filters with high-input impedance are presented. They can synthesize low-pass, bandpass, high-pass, all-pass, and notch filtering functions with a single CCII connected to five passive one-port RC elements. The active and passive sensitivities are calculated in order to determine the suitable domain for filtering applications. The quality factor and natural frequency of the proposed SCBs are insensitive to the voltage tracking error of the CCII. Experimental results that confirm the theoretical analysis were obtained. The circuits studied show the versatility of the CCIIs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

The new configuration employs a single second-generation current conveyor as an active circuit building block and four passive elements only. The configuration is advantageous in realizing a high Q filter without spread in circuit components.
