Silicon bandgap temperature sensor — The silicon bandgap temperature sensor is an extremely common form of temperature sensor (thermometer) used in electronic equipment. This directly affects the performance of a silicon pressure sensor, which relies on a highly fluid coupling between the process media and silicon chip. The word is a combination of thermal and resistor. PTAT circuits using either BJT or CMOS transistors are widely used in temperature sensors (where we want the output to vary with temperature), and also in bandgap voltage references and other temperature-compensating circuits (where we want the same output at every temperature). Current steering. The principle of the sensor is that the forward voltage of a silicon diode, which may be the base-emitter junction of a bipolar junction transistor (BJT), is temperature-dependent, according to the following equation: By comparing the voltages of two junctions at the same temperature, but at two different currents, IC1 and IC2, many of the variables in the above equation can be eliminated, resulting in the relationship: Note that the junction voltage is a function of current density, i.e. increasingly being used as temperature sensors.
