(a) The noise of an IC current source is measured at two different frequencies and is found to be in(250 Hz) 5 6.71 pA/ Hz and in(2500 Hz) 5 3.55 pA/ Hz . What are the values of inw and fci? (b) If the source is fed to a 1-kV resistance, fi nd the values of enw and fce for the noise voltage across its terminals. (c) Find the total rms noise En above 0.01 Hz if a 10-nF capacitor is placed across the resistor.
