Abstract: The measure of mechanical impact, vibration and shock are the few of the important aspect to be considered in designing mechanical moving mechanisms. This is evident on manufacturing plants that can be in the field of semiconductor, automobile, robotics and many more. This vibration, impact and shock measurement parameters are being measured by sensors. The sensor construction may be a strain gauge load cell, piezoelectric or piezoresistive transducer or the latest today is the Microelectro mechanical Systems (MEMS) sensor. The output may be in digital or analog with respect to the amount of G-force produced by such impact on the body. The measurement methods can be either slow or in a fast manner depending on the desired application. All the output of these sensors are then required to be digitized in order for the digital computing device for perform data evaluation. In this study, this will introduce a new technology in Successive Approximation Register (SAR) Analog to Digital (A/D or A-D) converter that can make the digitized the output of the vibration, impact or shock sensor with no missing codes on a 32-bit resolution digital representation while taking samples in a fast manner providing a more smoother readout of impact, vibration or shock subject sources.
