Solve for IC (in mA) given the transistor network shown:

Most of the following statements about integrated circuits arecorrect, but one is not. Which statement is NOT true? Select one: a. Transistors are constructed in a small area of an integrated circuit,and are connected to other transistors by wires that are embedded inthe integrated circuit b. Wires that carry signals may be embedded in a substrate without a shortcircuit because a short circuit would require a signal to cross areverse biased junction c. Each transistor on an integrated circuit is manufactured individually,one at a time d. An integrated circuit contains several layers

4. A MOS-C, p-type semiconductor is Si at 300K, Xo = 0.5 µm and doped with 6 x %3D 15 10/cm and operates under depletion bias. Assume that K, = 11.8 for Si and Ko = 3.9 for Sio?. Calculate the following parameters: (a) Calculate the depletion width (W) (b) Voltage gate (VG). %3D

A silicon (Si) npn bipolar transistor is doped with impurity concentrations of 10° cm, 10" cm, and 106 cm in the emitter, base and collector, respectively. The lengths of the emitter and collector length are 1 um and the base width is 500 nm. The device is operating at room temperature. (3) Determine the base current density in the transistor if the base emitter voltage VBs is forward biased with 0.5 V. Assume the base and emitter lengths are shorter than the diffusion length. (4) Explain why current gain is higher in npn transistors than in pnp transistors. (5) Sketch forward active lc vs. VE characteristics of the npn transistor as Vae increases with equal increments of voltage (e.g. 400 mv, 450 mv, 500 mv and 550 mV). You do not need to calculate values for collector current.
