A coupling capacitor is used to block dc current from an amplifier as shown in Fig. 11.86(a). The amplifier and the capacitor act as the source, while the speaker is the load as in Fig. 11.86(b).
(a) At what frequency is maximum power transferred to the speaker?
(b) If Vs = 4.6 V rms, how much power is delivered to the speaker at that frequency?
An NMOS device has parameters V_TN=0.8V, L=0.8µm, and k_n^'=120µA/V^2. When the transistors is biased in the saturation region with V_GS=1.4V, the drain current is I_D=0.6mA. A) What is the channel width W
