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.
