Abstract :
This paper describes new versatile building blocks for implementing analog functional circuits such as a multiplier, a squarer, and a square rooter. The input range of these circuits is over ±2.5 V with a high linearity of less than 0.5%. The -3 dB bandwidth of all discussed circuits has been simulated to over 90 MHz. The proposed computational circuits have high potential in evolving many signal processing circuits
