A FG-MOS implementation for low supply voltage applications of translinear networks for polynomial approximated functions

Abstract

This paper presents several new CMOS translinear topologies, suitable for static and dynamic analogue signal processing, realized by using floating-gate (FG)-MOSFETs. The possibility of controlling the apparent threshold voltage of FG-MOSFETs with multiple control gates offers an extra degree of freedom which can be successfully exploited in design of low voltage circuits. Also, the multiple floating gates were effectively used to simplify the circuit configurations. These topologies implement one or two variable objective functions, polynomial approximated and continued products decomposed. The objective functions must do not contain the time or frequency variables. The proposed topologies were analyzed for 0.5μm standard CMOS process via simulations for different objective functions.
