In this paper, new schemes for a squarer. multiplier and divider of complex numbers arc proposed. Traditional structural solutions tor each of these operations require the presence of some number of general-purpose binary multipliers. The advantage of our solutions is a removing of multiplications through replacing them by less costly squarers. We use Logan's trick and quarter square technique, which propo.se to replace the calculation of the product of two real numbers by summing the squares. Replacing usual multipliers with digital squares implies the reducing power consumption as well as decreases the comple.xity of the hardware circuit. The squarer requiring less area and power as compared to general-purpose multiplier, it is interesting to assess the use of squarers to implemenlation of complex arithmetic.
