Özet

Two new analog squarer circuits employing only seven MOS transistors are proposed in this study. The second proposed analog squarer is derived from the first one with slight modifications. MOS transistors used in both of the proposed analog squarers are operated in the saturation region. They are constructed as voltage input and current output. They have high input and high output impedances; consequently, they can be connected with other structures easily. Both of the proposed analog squarers have low power dissipation. However, they need some active component matching conditions. A four quadrant analog multiplier is given as an application example. Workability of the proposed analog squarers is verified by some SPICE simulation results. Additionally, some experimental tests are achieved.
