Two identical MOSFETs are placed in series as shown in Fig. 6.36. If both devices operate as resistors, explain intuitively why this combination is equivalent to a single transistor, Meq. What are the width and length of Meq?
Suppose f=20kHz and linear quantization is adopted. Calculate the PCM code when t0=10μs, maximum quantization error, the dynamic range, and the best and worst signal to quantization noise voltage ratio.
An initially charged capacitance discharges through a resistance. At one time constant, what percentage of the initial voltage reamins What percentage of the initial stored energy remains
A 480 V permanent magnet ac motor is consuming 10 kW at power factor 0.80 lagging. Its speed is 1800 rpm. The winding resistance is 0.5 ohms per phase. Core losses are 100 W.
Briefly describe the simplest heat treatment procedure that would be used in converting a 0.76 wt% C steel from one microstructure to the other, as follows:
How to solve : synchronous motor connted to infinite bus over short feeder with purely reactive impedance. Drawin P' - Delt ' characteristics showing A1 and A2 areas.
A decorative snowman with mass m = 15kg slides down a roof that is inclined at an angle of 30 º from the horizontal. The snowman slides a distance of 6.0m down the roof and off the edge, located 8.0m above the ground.
Determine Q and Q' output waveform for positive edge-triggered S-R flip-flop. Assume that positiveedge-triggered S-R flip-flop is initially reset.
Design a device that creates a voltage that is a damped oscillation with a frequency of 5 radians per second and a time constant of 3 seconds. In particular, explain how initial conditions are to be handled.
