WebA Practical BJT Amplifier using Coupling and Bypass Capacitors • AC coupling through capacitors is used to inject an ac input signal and extract the ac output signal without disturbing the DC Q-point • Capacitors provide negligible impedance at frequencies of interest and provide open circuits at dc. In a practical amplifier design, C 1 and C Web– So far, our treatment of small-signal analysis of amplifiers has been for low frequencies where internal capacitances do not affect operation. However, we did see that internal capacitances do exist and we derived the fT of transistors. Moreover, we spent some time looking at amplifiers modeled with a single pole. birthday cake with strawberry filling
