PACKAGE Thermistor IS

  -- Model an NTC thermistor with the B parameter equation

  GENERIC

    -- These parameters characterize a particular NTC thermistor

    B  : IN Float;
    R0 : IN Resistance.Ohms;
    T0 : IN Temperature.Kelvins := 298.15;

  PACKAGE NTC_B_Parms IS

    -- Calculate the temperature as a function of the thermistor resistance

    FUNCTION T(R : Resistance.Ohms) RETURN Temperature.Kelvins;
