Multi-signal generating circuit for sensor and method of generation thereof

The present invention relates to a multi-signal generating circuit for a sensor, the method of generation including the steps of: receiving an input signal from a generating circuit, and generating a plurality of reference signals based on the input signal and a plurality of physical parameters, wherein the reference signals change along with alteration of physical states of the generating circuit, and during the physical state alteration of the generating circuit the reference signals are equal to a plurality of objective values, the physical parameters corresponding to the physical state alteration of the generating circuit, respectively. Accordingly, the present invention generates the reference signals with reference to the physical parameters, so as to reduce the use of circuits to achieve the objects of reducing circuit areas and reducing cost.
