A 37.5 ko resistor is made of two strips connected in parallel, each one has 6 mm long, one strip is of intrinsic germanium and has 0.5 mm wide and 40 um thickness. Determine the width of the other strip in mm if its thickness is 10 um and is made of Ge doped with 15.625x10" donor atom/m', at the working temperature. The intrinsic carrier density of Ge is 3.125x10" m, and the electron and hole mobilities are 0.4 m/v.sec. and 0.2 m/v.sec., respectively
