An intrinsic semiconductor (Si) is doped with a p-type impurity. The minority carrier population in that material at room temperature is measured to be 11250 per cm^3. Given that, at room temperature, the hole mobility in Si as 350 cm^2/Vsec and ni= pi = 1.5 × 10^10 per cm^3, determine the electrical resistivity of the doped semiconducto?
What is the common-mode rejection ratio (in dB) if the output voltage is measured to be 2.0 Vp-p when the input terminals are connected together and a 0.1 Vp-p voltage is applied between the inputs and ground.
In a feedback system, the forward path has a transfer function of the form G(s)=k/(1+s/Omega_p) and the feedback path has a gain of k_fb which is less than unity. Calculate the bandwidth of the closed-loop transfer function
An LED with a rated range of VF = 1.4 V to 1.8 V at IF = 20 mA is connected to a driver circuit with a peak output of 14V. What value of current-limiting resistor would be needed to limit the LED current to a maximum value of 20 mA
in step index fiber the core of diameter D has a refractive n1, which is typically equal to 1.48. core is typically surrounded by the cladding of slightly lower index. Where n2=n1(1-delta). The parameter is simply called the index difference.
