A simple and low cost square-rooting circuit employing commercial devices
A simple square-rooting circuit based on available operational amplifiers (op-amps) and available CMOS transistor arrays (CD4007) is proposed in this paper. This circuit has simple structure. It consists of two NMOS transistors and three op-amps. The output voltage of circuit can be either positive or negative by setting gain which can be easily adjusted by varying the resistors. Experimental results by using CD 4007 and μa741 are given to verify the operation.
