Concept: CMRR (Common mode rejection ratio) is defined as the ratio of differential-mode voltage gain (A d) and the common-mode voltage gain (A c ). Mathematically, in dB this is expressed as: C M R R = 20 log | A d A c m |. Generally, it can be expressed as. C M R R = A d A c.For practical reasons, a pole with a short time constant, \(T_f\), may be added to the PD controller. The pole helps limit the loop gain at high frequencies, which is desirable for disturbance rejection. The modified PD controller is described by the transfer function: \[K(s)=k_p+\frac{k_ds}{T_fs+1} \nonumber \]

The open-loop gain of the amplifier will attempt to force the differential voltage to zero. As long as the input and output stays in the operational range of the amplifier, it will keep the differential voltage at zero, and the output will be the input voltage multiplied by the gain set by the feedback.Hormone changes or medical problems can also cause unintentional weight gain. This may be due to: Bloating, or swelling due to a buildup of fluid in the tissues can cause weight gain. This may be due to menstruation, heart or kidney failure, preeclampsia, or medicines you take.
