In this paper, a mixed mode square-rooting circuit based on CMOS transistors operating in saturation region is proposed. The major advantage over the other square-rooting circuits is that it has two inputs (voltage input V<SUB>i</SUB> and current input I<SUB>i</SUB>), and its output V<SUB>O</SUB> can be square-rooting function of either V<SUB>i</SUB> or I<SUB>i</SUB>. The input range is analyzed. Simulation results are carried out by PSpice program. They find that the circuit can operate at ± 2_V power supplies, the voltage input range is about 300㎷, the relative error as I<SUB>i</SUB>=0_A and varied is 1.869% the current input range is about 100㎂, the relative error as V<SUB>i</SUB>=0_V and varied is 1.865%, and the voltage output range is about 300㎷. Experimental results are done to confirm operation of the circuit by using CD4007 transistor arrays.
