摘要： A temperature-related voltage generating circuit has an input terminal receiving a control voltage independent of temperature, and an output terminal delivering a temperature-related control voltage. The input and output terminals are connected together through at least an amplifier stage adapted to set an output reference voltage from a comparison of input voltages. The voltage generating circuit also includes a generator element generating a varying voltage with temperature and connected between a ground voltage reference and a non-inverting input terminal of the amplifier stage. The amplifier stage has an output terminal adapted to deliver a multiple of the varying voltage with temperature to an inverting input terminal of a comparator stage. The comparator stage has its output connected to the temperature-related voltage generating circuit and a non-inverting input terminal receiving the control voltage independent of temperature to evaluate the difference between the control voltage independent of temperature and said voltage being a multiple of the varying voltage with temperature and to output a temperature-related control voltage having at room temperature a mean value which is independent of its thermal differential and increases with temperature. The voltage generating circuit can be incorporated into a regulator for a drain voltage of a single-supply memory cell.
