Abstract
A tunable CMOS transconductor is presented. Input rail-to-rail operation is achieved using floating-gate MOS (FGMOS) transistors. Tuning is also obtained using FGMOS transistors, which are biased in weak or moderate inversion to achieve precise output current scaling. A technique to set the proper transconductance value independently of process or temperature variations is also included. Measurement and simulation results using a 0.5um CMOS technology are presented to confirm all the circuits and strategies proposed.
