Keywords: Active C circuits Quadrature sinusoidal oscillator Resistorless Differential voltage current-controlled conveyor transconductance amplifier (DVCCCTA) a b s t r a c t This paper presents a new realization of resistorless mixed-mode (i.e. both voltage-mode and current-mode) quadrature sinusoidal oscillator using a new active building block (ABB)(More)
In addition to the recently proposed full-wave rectifier by Prommee et al. [25] using voltage-mode (VM) two-cell winner-takes-all (WTA) circuit, we present current-mode (CM) precision full-wave rectifier using CM two-cell WTA circuit. The popular Lazzaro's CM WTA circuit has been employed for the purpose and there is no requirement of inverting the input(More)
The paper deals with a pair of current-mode sine-wave oscillator circuits. Both these circuits are implemented using positive second-generation current conveyors (CCII+). The principle of the first oscillator is based on a conventional Wien-bridge network. However, this implementation suffers from the use of a floating ca-pacitor, which can be unacceptable(More)
This article presents a voltage-mode universal biquadratic filter (low-pass, high-pass, band-pass functions), based on current controlled current conveyor transconductance amplifiers (CCCCTAs). The features of the circuit are that: the quality factor and pole frequency can be tuned orthogonally via the input bias currents: the circuit description is very(More)
The main aim of this work is to demonstrate the use of electronically controlled second-generation current conveyor in providing electronic control to the condition of oscillation (CO) of a new active RC sinusoidal oscillator. Electronic control of the CO, which is independently set and does not affect the oscillation frequency, is enabled by the use of an(More)
