The common mode rejection ratio is adifferential amplifierand the op amps are amplified in with the differential input. Hence the CMMR ratio can be applied to the operational amplifier. By using the condition of common mode rejection ratio, i.e. when both the input of the amplifier has same ...

The gain error is less than 0.65% and the common-mode rejection ratio (CMRR) is higher than 130[Formula: see text]dB at 1[Formula: see text]kHz. Simulation results show that the output voltage of CSM circuit varies linearly with the CSM input sense voltage....
In this work, we introduce the design of a 16-channel in-pixel neural analog front end that employs a current-based summing approach to establish a common-mode feedback loop. The primary aim of this novel structure is to enhance both the system common-mode rejection ratio (SCMRR) and the...
