A voltage regulator circuit uses a Zenerdiode that exhibits a total voltage of 5.2 V at 20 mA and has aresistance Rz = 20 W. The regulator operates froma 10 V supply and has a 1 kW load.
A) Use the node voltage method at the output node to derive anexpression for Vo in terms of Vs.
B) Find the value of R (use the regulator circuit diagram givenin class) to get an output voltage vo = 5 V.
C) Find the line regulation.
D) Find the load regulation.
E) Find the change in vo resulting from a ±1 V change in the supply voltage.
A time varying capacitor is characterized by the charge- voltage equation q(t) = C(t)v(t)
determine the transfer function of a 4th order lowpass butterworth filter with a 3-dB cutoff frequency of 3.4 kHz and passband gain=1. Design the circuit using MFB topology. Design two sections with an order of 2.
Describe what causes the human body to have resistance and what factors can affect the resistance of the human body.
Two identical CS amplifiers are connected is cascade. First stage is fed with a source Vsig having a resistance Rsig = 100k Ohm. A load resistance Rl = 10k Ohm is connected to the drain of the second stage.
Do you think that an electric automobile based on capacitive energy storage is feasible?
Assume you have a 3-bit pre-packaged counter. You cannot modify thecounter except for hooking logic to the inputs and outputs. Thecircuit has synchronous load and synchronous reset control inputs.The loadable inputs are a2, a1, and a0 (with a2 as ..
A series circuit has a resistance of 1 ohm and an inductance of 1 ohm. The voltage across the circuit has an amplitude of 15 volts and a phase shift of 30 degrees. What is the current of the circuit in frequency and time domain
A control system is needed to control a small shopping center parking lot lighting system and the exterior lighting for the building. The design specifications require that the parking lot lighting and the exterior lighting turn on at dusk automat..
Design an elevator controller for a simple two-floor elevator. On the 1st floor, there is only an up button, and on the 2nd floor, there is only a down button. Within the elevator, there are two buttons: door open and door close.
A solid spherical conductor of radius a is surrounded by a concentric spherical conducting shell of inner radius b and outer radius c. The region between the conductors, a
Design a 4-bit serial equality comparator. That is, if we have a3a2a1a0 = b3b2b1b0, then eq = 1. Note that a3a2a1a0 is stored at register 1, while b3b2b1b0 is stored at register 2. You have to implement the same function using a serial equality co..
Once INIT is negated, Z should remain 0 until X has been 0 for two successive ticks and 1 for two successive ticks, regardless of the order of occurrence. Then Z should go to 1 and remain 1 until INIT is asserted again.
