Unformatted text preview: (+/-3000) = 0. Figure 1. 2. Fig. 2 shows a circuit for charging a 12V battery. Assume that the forward conducting diode exhibits a constant voltage drop Vd=0.7V. a. If vs is a sinusoid with 24V peak amplitude, find the fraction of each cycle during which the diode conducts. b. Find the peak value of the diode current and the maximum reverse-bias voltage that appears across the diode. Figure 2. 3. A MOS capacitor has an n+ polysilicon gate, a 450 Angstrom thick gate oxide, and an n-type substrate with donor concentration Nd=7.5x10 16 cm-3 . a. If the gate charge is Qg = 2x10-7 C/cm 2 , sketch the charge density through the MOS capacitor. b. For the gate charge in part a), what is the gate-bulk bias V GB ?...
