“…The block diagram and the equivalent circuit of the IZC-CDBA are shown in Figure 1a and Figure 1b, respectively. The CMOS structure of IZC-CDBA is presented in Figure 2(a) which is a marginally modified version of the CDBA structure suggested in [30]. Figure 2(b) shows the IC AD844 based structure of the IZC-CDBA block.…”

This paper aims to introduce a new current-mode precision full-wave rectifier configuration using a single inverted Z-copy current differencing buffered amplifier (IZC-CDBA) and two nMOSFETs. The unique feature of the proposed configuration is that it can simultaneously produce both the inverting and non-inverting rectified outputs without changing its architecture. Only active components make the configuration more suited for IC implementation. Moreover, it features low input impedance and high output impedance, making it fully cascadable. In addition, the new design enjoys extremely high-frequency operations. The effects of non-ideal transfer gain and parasitic impedances on the designed circuit are also explored. PSPICE simulations test the functionality of the proposed circuit for two distinct types of IZC-CDBA realization. The CMOS-based realization is checked through TSMC 0.18 μm level-7 technology parameters. The average DC current output, input dynamic range (± 450 μA), power consumption, temperature, total harmonic distortion, noise, and Monte-Carlo studies are performed to judge the efficiency level. The findings of the simulations match up nicely with the theoretical analysis. RMS and average value computation for a sinusoidal signal are also provided as an application of the suggested full-wave rectifier.

“…The PSPICE simulation results of these normal filters and inverse filters using CMOS CDBA implemented with 0.18µm CMOS technology parameters have been provided over the frequency range 10 kHz-50 MHz. Whereas most of the work has been focused on second-order inverse filters of various kinds, Borah, Singh and Ghosh in [31] have given a realization of a sixth-order inverse band-pass filter. The circuit consists of two CDBAs and eight impedances, which has been practically realized from four AD844-type CFOAs but employs nine capacitors and as many resistors.…”

This paper traces the history of the evolution of inverse analog filters (IAF) and presents a review of the progress made in this area to date. The paper, thus, presents the current state-of-the art of IAFs by providing an appraisal of a variety of realizations of IAFs using commercially available active building blocks (ABB), such as operational amplifiers (Op-amp), operational transconductance amplifiers (OTA), current conveyors (CC) and current feedback operational amplifiers (CFOA) as well as those realized with newer active building blocks of more recent origin, such as operational transresistance amplifiers (OTRA), current differencing buffered amplifiers (CDBA) and variants of current conveyors which, although not available as off-the-shelf ICs yet, can be implemented as complementary metal–oxide–semiconductors (CMOS) or be realized in discrete form using other commercially available integrated circuits (IC). In the end, some issues related to IAFs have been highlighted which need further investigation.
