Unformatted text preview: when the input changes over the range of 5V (sketch V B and V C versus V A ). For a 5 V peak, 100 Hz sinusoid applied at A, sketch the waveforms resulting at nodes B and C. Assume that each diode has a 0.7 V drop when conducting. Fig. 1 3- For the circuits in Fig. 2, each utilizing an ideal diode, sketch the output for the input shown. Explain how you obtain these waveforms. Assume CR>>T. Fig. 2 4- Calculate the built-in voltage of a junction in which the p and n regions are doped equally with 10 16 atoms/cm 3. Assume n i 10 10 atoms/cm 3 . With no external voltage applied, what is the width of the depletion region, and how far does it extend into the p and n regions?, If the cross-section area of the junction is 100 m 2 , calculate the junction capacitance C j .
