“…To enable signal processing at higher frequencies than it is currently allowed by standard op amp based solution (Fig. 2c), the diodes are directly connected to the high impedance terminal Z of the current conveyor CCII as in [4,5,6,7]. Subsequently, the differential current inputs of the universal voltage conveyor are used with advantage and therefore only two diodes need to be used.…”

“…Significant improvement in high frequency signal rectification has been achieved by using active elements with highimpedance current outputs, to which the diodes are connected. In [4,5,6,7] the same voltage-mode full-wave rectifier using two second-generation current conveyors and four diodes is presented that can be used to process signals at frequencies up to 100 kHz. The frequency range can be further extended using the voltage [4,7] or current [6,7] biasing scheme.…”

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.

This paper presents a new current conveyor (CCII+) full-wave rectifier for low frequency/small signal medical applications. The proposed rectifier is based on the current conveyor full-wave rectifier proposed previously, but the proposed rectifier is better in view of no need diodes to rectify, and no need bias sources to overcome the zero crossing error. It needs only two CCII+s, two resistors, and three simple current mirrors, which is easy for IC implementation and for building in many countries. The PSPICE simulation with the current conveyor CCII+ in the current feedback opamp AD844 IC and the 2N2222 bipolar current mirror shows the good low frequency/small signal rectification, the operation voltage of down to 6 μV .

“…For this purpose, the second generation current conveyor (CCII) is used in the fullwave rectifier discussed in [5]. The same structure from [5] using two active elements and four diodes is also analyzed in [6]- [8]. As two diodes are grounded, the voltage- [5], [8] or current- [7], [8] biasing scheme can be used to further extend the operational region.…”

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.
