  This paper proposes four quadrant analog multiplier using CMOS-memristor
circuit. Currently, there are plenty of analog multipliers using resistors and
CMOS transistors. They can attain perfect multiplication but have several
disadvantages such as lower processing speed, higher power consumption and
larger chip areas. Memristor based circuits are introduced to resolve the
mentioned drawbacks. In this paper current mode four quadrant multiplier based
on squaring circuits is taken as a framework, and CMOS transistors are replaced
with memristors. The circuit design is simulated with SPICE, and variability
analysis and performance variation with temperature is performed. The proposed
circuit allows faster processing with retained data while dissipating less
power retaining the multiplication characteristics.
