Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0032] The present invention utilizes the operating characteristics of CMOS transistors in the sub-threshold region to design a reference source circuit with low power consumption, low temperature coefficient and small area. By using CMOS with different gate thresholds to realize stable voltage output, stable voltage output with low temperature coefficient is realized. The voltage and current characteristics of a CMOS transistor operating in the subthreshold region are shown in the following expression:
[0033] (2)
[0034] in V TH is the gate threshold voltage with a positive temperature coefficient and V T is the thermal voltage ( V T =k B T / q ) has a negative temperature coefficient. K is the width-to-length ratio of the CMOS tube, I D is its drain current, u is the c...
