... The midband gain, A m , is obtained from the midband equivalent circuit of the common-source amplifier. This is shown in Figure 12.24. The equivalent circuit is obtained by short-circuiting ... The midband gain is obtained by short circuiting all the external capacitors and open circuiting the internal capacitors. Figure 12.14 shows the equivalent for calculating the midband gain. ... electronic circuits are not suitable for integrated circuits (IC) because of the large number of resistors and the large coupling and bypass capacitor required for biasing discrete electronic circuits....
