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

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 obtainedFile in questo prodotto:
