A reconfigurable translinear cell architecture for CMOS field-programmable analog arrays

This paper presents a CMOS reconfigurable translinear cell intended to be part of a field programmable analog array. The cell is composed of a recently developed wide dynamic range translinear element and programmable current sources, current mirrors and capacitors. An FPAA built with this cell is able to implement the most common primitives of translinear design, such as, multiplication, division and log-domain filtering. An application example, consisting in a two quadrant multiplier, is presented in this paper.
