Abstract :
A current-mode cell based on the square-law characteristic of MOS transistors in saturation is revisited to extend its functionality. The original structure was reported to provide a squaring operation. However, by biasing the circuit differently the circuit can perform the inverse operation and operate as a geometric-mean/square-rooter. This is illustrated with experimental results
