Abstract

This paper presents techniques for achieving various combinations of zero-incremental and zero-gross-sensitivity integrated (activeRCfilter circuits. Use is made of the fact that in the usual integrated circuit, all the capacitors have the same temperature coefficient, and similarly with the resistors. It is shown how this may be exploited to achieve for the system complex pole pair: 1) zero incremental sensitivity to temperature variations at a single temperatureT_{1}; 2) identical values at any two temperaturesT_{1}, T_{2}3) incremental sensitivity atT_{1}and identical values atT_{1}, T_{2}; 4) identical values atT_{1}, T_{2}, T_{3}. The techniques are applicable whenever each member of the same class of elements (such as resistors, capacitors, etc.) has the same relative change from the nominal.
