The digitally controlled current conveyor has been used to realize a novel digitally controlled reconfigurable continuous time current mode first order multifunctional filter. The realized filter can provide first order current mode low pass, high pass and all pass responses without any component matching constraints. The pole frequency of the continuous(More)
In this paper a Tunable four phase sinusoidal quadrature oscillator is realized using CMOS multi-output second generation current conveyors (MOCCIIs). The circuit uses only two CMOS MOCCII and provides four phase quadrature voltage outputs with equal magnitude at the oscillating frequency. The oscillator also exhibits independent frequency control. The(More)
This paper presents a voltage mode cascadable single active element tunable first-order all-pass filter with a single passive component. The active element used to realise the filter is a new building block termed as differential difference dual-X current conveyor with a buffered output (DD-DXCCII). The filter is thus realized with the help of a DD-DXCCII,(More)
A novel and simple circuit for precision rectifier using second-generation current conveyor (CCII) is presented in this article. The circuit basically uses a CCII-based voltage mode bi-phase amplifier, which has been used as full-wave and half-wave rectifiers. To switch the bi-phase amplifier from non-inverting to inverting mode, a MOSFET and a CCII-based(More)
A mixed-mode three phase sinusoidal oscillator (MTSO) employing Second Generation Dual-X Current Conveyor (DXCCII) as the active element is presented. A feedback scheme consisting of two lossy integrators followed by a lossless inverting integrator is employed to obtain three voltage-mode and three current-mode sinusoidal signals simultaneously. The(More)
This paper presents two improved precision rectifiers, each employing two active elements and two MOS transistors. The new circuits are advantageous when compared to the most recent work [5] by enjoying high input impedance and resistor-less realization, which makes them ideal for CMOS implementation. High precision and wide frequency operation of the(More)
