Abstract :
A new technique is proposed to stabilize changes in the transconductance of CMOS transconductors, arising out of changes in environmental temperature. The method uses conventional negative feedback technique. Since transconductors are used as the basic building blocks in various gm-C filters, stabilizing the transconductance will bring stability in the frequency and quality factor of the filters built from these transconductors
