Webfunction. For the low-frequency segment (i.e., TL(s)) of the magnitude plot this will be designated by fL (or ωL =2π fL). In a practical case the function TL(s) may have several poles and zeros at low frequencies. The pole which is closest to the flat mid-band value is known as the low frequency dominant pole of the system. Thus it is the pole of highest … WebWith these capacitances, the high frequency small-signal model of the BJT becomes (Fig. 5.67) Note the use of the Vπ notation in this small-signal model. Your textbook has switched to sinusoidal steady state notation for this high frequency discussion. The high frequency small-signal model in Fig. 5.67 also
