Sometimes amplifiers are connected together (cascaded amplifiers). In such cases, the total gain is the product of the individual amplifier voltage gains: A V = A V1 × A V2. If the gains are in dB, the gains are added instead of multiplied. When amplifiers are connected together, they are frequently connected with capacitors, as shown below.

If it is a linear (voltage) amplifier then the relationship between input and output is V out = gV in +c . Here g is a constant called the gain of the amplifier, while c is a constant called the offset. The amplifier is called linear because the graph representing the above equation is a straight line. Naturally, there is a range of voltage over which an amplifier operates linearly.
In order to operate transistor as an amplifier, biasing is done in such a way that the operating point is in the active region. For an amplifier the Q-point is placed so that the load line is bisected. Therefore, in practical design V CE is always set to V CC /2. This will confirm that the Q-point always swings within the active region.

amplifier system. The frequency response limitation at low frequency occurs because of coupling and by-pass capacitors used in the amplifier circuit. For single-stage amplifiers, i.e., CE, CB..CS,CG amplifiers these capacitors come in series with the signal path (i.e., they form a loop in the signal
And the op-amp amplifies this with a factor 1+R1/R2 to it's output. The noise gain factor for the op-amp + input current noise is: (1+R1/R2).Rs.R3/(Rs+R3) . Please note that the unit of this gain factor formula is: Ohm (or Volt per Ampere), which is necessary because we convert Ampere to Volt, so we need to multiply by Ohm.

The unit impulse response h (n) was given by. h(n) = 0, | n | > DM - 1 h(n) = 1, | n | ≤ DM - 1 (1) where D is the decimation factor of the decimator and M is the delay factor of the comb filter.

The 1-dB compression point for an amplifier, for example, is where the linearity of the component begins to degrade. Under linear conditions, a 1-dB rise in input power will result in a 1-dB increase in output power. When the increase at the output is 1-dB less than the increase at the input, it is said to be the amplifier's 1-dB compression point.

The CS-CC cascade two-stage amplifier is a good multistage configuration because the CS and CC amplifiers together provide some very desirable characteristics. The CS amplifier makes up the first stage and is capable of providing high voltage gain. The input impedance of the CS is a function of Rg1 and Rg2 and is generally very high. Since the power gain specification is referenced to a 500 [ohms] source and a 5000 [ohms] load, the cascade voltage gain is from -45 to +60 dB.
