1- A 10kΩ resistor is made of two strips connected in parallel, each one has 40µm thick, and 6mm long, one strip is of intrinsic germanium and has 0.5mm wide. Determine the width of other strip if it made of Ge., doped with 10 21 donor atom/cm3 ,at the working temperature. The intrinsic carrier density of Ge is 2.5 × 1019 m -3 , and the electron and hole mobilities are 0.4 m2 /V.sec. and 0.2 m2 /V.sec. respectively.
