Abstract :
The aim of this paper is to design analog circuits which develop different computations. This work generalizes the basic idea of the implementation of squaring and square root circuits proposed before to generate nth-power-law circuits and nth-root circuits. The MOSFET´s work on the weak inversion region which allows implementing different kinds of non-linear functions. Fundamental circuit operations were demonstrated and the performance of the circuits using SPICE (simulation program with integrated circuit emphasis) was confirmed. The design was developed for a 0.5 ¿m-technology.
