The logarithmic amplifier of Fig. 8.24 must "map" an input range of 1 V to 10 V to an output range of -1 V to -1:5 V.
(a) Determine the required values of IS and R1.
(b) Calculate the small-signal voltage gain at the two ends of the range.
A certain amplifier has pole frequencies of f1=f2=f3=50MHz. The DC open-loop gain is 10^5. Find the pole frequency fc for the fourth pole so that the phase margin is 30 degrees for beta = 0.1 Also, find the corresponding gain margin.
the N-type P-type doping levels of a silicon p-n junction are nd=na= 5x10^16 cm^-3 caltulate the built in voltage Vbi a) at a room temperture b) at 300c c) at 700 c (ni= 1.10x1018 cm^-3) does a negative value for Vbi mean anything
How many kg of coal with energy content of 24 MJ/kg would be equivalent to energy used by a 100-W light bulb burning constantly for the whole year. Coal to electricity conversion efficiency is 30%.
