Analog multiplier design with CMOS-memristor circuits

Abstract

CMOS-transistors circuits have been used as a conventional approach for designing an analog multiplier in modern era of industrial electronics. However, previous studies have shown, that based on the working region of transistors, such as saturation or weak inversion regions, the circuit may face issues with output ranges and accuracy. One possible solution to that problem could be choosing CMOS-memristors as a basis for the circuit. Although memristor research is still a growing and promising field, one could argue that its implementation could bring many benefits such as increased circuit density and superior computation speeds, etc. Additionally, the era of Moore's Law of downscaling the size of transistors is to eventually come to an end. No one knows whether the end of a scaling paradigm is to happen within the next five or twenty years. Hence, the research on this particular subject is quite important. This paper proposes an analog multiplier design with CMOS and memristive components. Mainly, the aim of the paper is to compare the power consumption and overall characteristic of the multiplier such as the accuracy and the output range to that of the conventional multiplier. The designed circuit is expected to be suitable for low power applications, and it is built using 18um CMOS technology. The circuit simulations will be conducted using SPICE software. Finally, the effects of channel modulation and temperature on the multiplier performance will be discussed.
