Never did just guess - can use linear tempco device and put its output to amp with parabolic transfer characteristic . Can tunnel diode serve that purpose ?
or , same linear tempco device output goes to ideal rectifier (temp dependent device output should be biased so its output must be 0 for parabola min). Got linear result can be smoothed by simple diode/resistor circuit to get parabola alike output .
surianova,
I don't understand the question. Are you trying to design acuircuit that provides a current that has a parabolic I = (C1) + (C2)T^2 variation with respect to temperature?
