Abstract :
A simple technique for stabilising the transconductance of CMOS transconductors against temperature variations, with no need of external frequency reference signals, is presented. Accurate electrical simulations demonstrated that a 2.6% maximum transconductance variation over the temperature range -55-150°C and a 600% tuning range can be obtained.
