Transducer Type IC Sensors The IC transducer is small with a low thermal mass and a fast response time. Although each type of sensor uses different technology to capture images, both CCD and CMOS imagers use metal-oxide semiconductors, having the same degree of sensitivity to light, and no inherent quality difference Since sensors cannot replicate an ideal transfer function, several types of deviations can occur which limit sensor accuracy: Since the range of the output signal is always limited, the output signal will eventually reach a minimum or maximum when the measured property exceeds the limits. Presently, the most popular manufacturing technology for accelerometers (as well as many other types of sensors) is MEMS.
