  • Patent number: 6750641
    Abstract: An exemplary method and circuit for temperature nonlinearity compensation and trimming of a voltage reference are configured to provide for two-point independent trimming of each of the curvature coefficients within the Taylor approximation curve. A voltage reference circuit is configured with a translinear circuit having an input current source. The translinear circuit comprises a translinear unit having a plurality of output currents corresponding to the curvature coefficients of the Taylor row approximation curve, with the output currents coupled to a control input terminal of the voltage reference. During trimming, at a first nominal temperature, the input current source is trimmed to a zero value, and each of the curvature terms of the Taylor approximation will be equal to zero value.
