A new type absolute temperature-sensor with the measurable temperature range between 77 K and 400 K based on the forward voltage change due to the ambient temperature is proposed and demonstrated. In this temperature-sensor the forward ac voltage change or the forward ac current change at the pn junction diode due to the temperature change is measured for a constant amplitude of superimposed ac small signal of current δ<i>I</i> or voltage δ<i>V</i>, respectively, on the constant forward dc current <i>I</i><sub>0</sub>. This sensor has merits that it can be calibrated at only one temperature point, that output voltage is proportional to the absolute temperature <i>T</i> and that the measurement can be done independent of the ground point, since the ac signal circuits can be isolated from dc bias voltage circuits.
