Abstract
In this chapter, firstly the main methods for the signal recovery from noise will be introduced and discussed. Then, the lock-in technique, for the detection of sensor signals embedded into noise, will be described in detail. In this sense, an analog lock-in amplifier (to be used in sensor interfaces) as a complete integrated circuit, designed at transistor level in a standard CMOS technology (AMS 0. 35 μm), will be presented, together with some experimental results on gas sensors. This integrated solution improves sensitivity and resolution of the complete gas measurement system. Finally, we also propose the block scheme and operation of a high-precision high-accuracy fully-automatic integrable analog lock-in amplifier, also employed for the detection of small quantities of gases.
