ABSTRACT:In this paper, design of a CMOS tunable versatile filter using current conveyor (CC) is presented. The filter is realized at the same time as on the chip is tunable for low pass, band pass, high pass, and elliptical notch filter. The circuit is utilizes two current conveyors, one Operational Trans-conductance Amplifier (OTA), four resistors and two grounded capacitors, ideal for integration. It has only one output terminal and the number of input terminals may be used. Further, there is no further requirement of component matching in the circuit.

Abstract-This paper deals with the design of a fast voltagemode full-wave rectifier, where universal voltage conveyor and second-generation current conveyor are used as active elements. Thanks to the active elements, in theory the input and output impedance of the non-linear circuit is infinitely high respectively zero. For the rectification only two diodes and three resistors are required as passive elements. The performance of the circuit is shown on experimental measurement results showing the dynamic range, time response, frequency dependent DC transient value and RMS error for different values of input voltage amplitudes.

“…The current conveyor was introduced in 1968 for the first time [10] and labeled as first-generation current conveyor CCI. Later, the second-(CCII) [11] and third-generation current conveyors [12] (CCIII) were presented. These active elements receive considerable attention and are used in applications where the wide frequency bandwidth or output current response is necessary.…”

Abstract:In this paper, new minimal configuration precision fullwave rectifier is presented. The structure employs one current and one voltage conveyor and only two diodes. It enables to process both low-voltage and low-current signals. Compared to the op amp based circuit, the proposed circuit is able to rectify signals up to 500 kHz and beyond with no or small distortion. Experimental measurements are performed that show the feasibility of the new precision full-wave rectifier.
