A CS amplifier using an NMOS with gm = 3.8 mA/V is found to have an overall voltage gain of -16 V/V. What value should a resistance RS inserted in the source lead have to reduce the overall voltage gain to -8 V/V ?
A sensor with a nominal resistance of 50 ? is used in a bridge with R1 = R2 = 100 ?, V = 10.0 V, and R3 = 100 potentiometer. It is necessary to resolve 0.1 changes of the sensor resistance. A) At what value of R3 will the bridge null
What is frequency sensitivity of the demodulator? What is the value of A_m for which the carrier component is reduced to zero for the second time
(a) Compute the minimum voltage that the output voltage across R1 falls to when both capacitors C1 and C2 are present. (b) Using the same model for D1, compute the maximum voltage that the output voltage across R1 rises to.
