Abstract
This paper proposes the analog CMOS squarer and the four-quadrant analog CMOS multiplier. The major advantages of the proposed circuits are low voltage supply, multifunction of output, and insensitive to the threshold voltage variation caused by body effect. The versatile squarer has two inputs (V in and I in ). Its output can be the square of V in or the square of I in . The versatile four-quadrant multiplier has four inputs (V X , I X , V Y , and I Y ). Its output can be the product of V X and V Y , the product of I X and I Y , the product of V X and I Y , or the product of V Y and I X . Therefore, the proposed circuits can be applied more than conventional circuits and have good performance. Second-order effects and frequency response are analyzed. Simulation results have verified the workability of the circuits. Experimental results are done to confirm the operation of the circuits.
