Q/ A (10 KQ) resistor is made of two strips connected in parallel, each one has (40 um) thick, and (6 mm) long. One strip is of intrinsic germanium and has (0.5 mm) wide. Determine the width of other strip if it made of Ge., doped with (102) donor atom/cm2,at the working temperature. The intrinsic carrier density of Ge, is (2.5x10"m), and the electron and hole mobilities are (0.4 m/V.Sec. , and 0.2 m'/V.Sec.) respectively.
