ABSTRACT:
Provided is a low power random bit generator utilizing a multiplying digital to analog converter (MDAC) which is used in a switched capacitor amplifying circuit and an analog to digital converter with a pipeline architecture. The low power random bit generator includes: an MDAC, outputting a predetermined analog voltage formed by using a ground voltage, a reference voltage, an initial voltage and a digital signal; a comparator, outputting a direct current (DC) voltage determined by comparing the analog voltage with the ground voltage; and a data storage unit, storing a predetermined digital signal corresponding to the DC voltage, and outputting the digital signal.
