Abstract :
An improved approach to design the approximate squaring function is presented in this paper. It is implemented through a simple combinational logic circuit with fewer transistors. In addition, the maximum relative error (MRE) and average relative error (ARE) of squaring approximation are both improved compared with the previous methods. The algorithm is implemented by a VLSI design of 7-bit approximate squaring function.
