<p>The present invention relates to a circuit for measuring the acceleration of a three-axis acceleration sensor. A circuit for measuring the acceleration of a three-axis acceleration sensor according to the present invention includes a three-axis acceleration sensor which is connected in parallel, and outputs a corresponding signal by detecting acceleration applied to three-axis directions of X, Y, and Z; a demultiplexer which outputs a three-axis signal outputted from the three-axis acceleration sensor through a single path; and a multiplexer which includes an amplifier which amplifies the output signal from the demultiplexer and distributes the output signal of the amplifier to each axis in the back end of the amplifier, and a sample & amp which samples the analog signal of each axis outputted from the multiplexer and stores it; an analog/digital converter which converts the analog signal outputted form a hold circuit part and the amplifier into a digital signal.</p> |
