Derive the VDS equation as a function of VGS, for the following MOSFET based amplifier. Please use current equations of MOSFET, as discussed in the class. As per class discussion, we know this circuit can be used as an AC amplifier. Please discuss how can the gain of this AC amplifier, be enhanced
Example 2: To move charge q from point a to point b requires -30J. Find the voltage drop vh if: (a) q = 6 C, (b) q - -3 C.
A collections of human skulls is divided into three classes A, B and C according to the value of a length-breadth index X. Skulls with X<65 are classified as A (long headed), those with 6570 as C (short headed). The percentages in the three classes in this collection are 58, 38 and 4. Find approximate the mean and standard deviation of X, on the assumption that X is normally distributed.
A thermometer reads 95.xy°C and the static correction given in the correction curve is -0.0y°C. Hence,
x = 7 and y = 2
Determine the true value of the temperature.
Aim: Determine the true power dissipated in the load of a single-phase half-wave rectifier fed from a 220 V 50 Hz supply. The load resistor is equal to the last two numbers of your
student number + 10 ohm.
