In DC to low-frequency sensor signal-conditioning applications, relying on the common-mode rejection ratio (CMRR) of an instrumentation amplifier to provide robust noise rejection in harsh industrial ...
In Part 1 (click here), we learned how an old technique known as servo feedback can remove dc offsets in a dc-coupled gain block, without putting any components, especially capacitors, in the ...
Many sensors have a small analog signal that rides on top of a larger dc pedestal. For these circuits (Fig. 1), the signal must be ac coupled and amplified before it’s digitized. The feedback of an ...
A research team led by Prof. MENG Guowen from the Institute Solid State Physics, Hefei Institutes of Physical Science (HFIPS) of Chinese Academy of Sciences (CAS), cooperating with Prof. WEI Bingqing ...
