Abstract :
Two MOS squarer circuits are presented. One implementation operates on sampled-data signals, while the second uses continuous-time operation. Both squarers achieve the square-law function with MOS transistors operating in the nonsaturation region biased with zero drain-to-source voltage. Benefits of nonsaturated operation are discussed. The sampled-data squarer is practically independent of component mismatches and clock pulse-width mismatches
