CIRCUIT FOR MEASURING ACCELERATION OF THREE-AXIS ACCELERATION SENSOR

摘要

Disclosed herein is a circuit for measuring acceleration of a three-axis acceleration sensor. The circuit for measuring acceleration of a three-axis acceleration sensor includes: three-axis acceleration sensors connected to one another in parallel and sensing the respective accelerations applied to three axes directions of X, Y, and Z axes to output corresponding signals; a demultiplexer outputting three axes signals each output from the three-axis acceleration sensors through a single path; and an amplifier amplifying the output signal from the demultiplexer, and further includes, at a back-end of the amplifier, a multiplexer distributing a signal output from the amplifier to the respective axes, a sample and hold circuit unit sampling and storing an analog signal of each axis output from the multiplexer, and an analog-to-digital converter converting an analog signal output from the amplifier into a digital signal.
