WebGain is maximumwhen = o (i.e. the gain coefficient is at resonance). At non-resonant frequencies the gain follows the homogeneously broadened characteristics of a two level atom(i.e. Lorentzian profile). The gain BWfor this spectrum is typically expressed as the (Full Width at Half Maximum) FWHM g2T2. 2 g g with Tp20.1s g3THz http://rfic.eecs.berkeley.edu/~niknejad/ee142_fa05lects/pdf/lect9.pdf

WebGain Compression Vi Vo dVo dVi Vi Vo dVo dVi The large signal input/output relation can display gain compression or expansion. Physically, most ampliﬁer experience gain compression for large signals. The small-signal gain is related to the slope at a given point. For the graph on the left, the gain decreases for increasing amplitude. WebNov 29, 2024 · The Voltage Gain of the common emitter amplifier is equal to the ratio of the change in the input voltage to the change in the amplifier’s output voltage. Then ΔVL is Vout and ΔVB is Vin. But voltage gain is also equal to the ratio of the signal resistance in the Collector to the signal resistance in the Emitter and is given as:

WebGain is a linear operation. Gain compression is not linear and, as such, its effect is one of distortion, due to the nonlinearity of the transfer characteristic which also causes a loss of 'slope' or 'differential' gain.
