The current in a 20 mH inductor is known to be i = 40 mA, t < 0; i = A,e~mm[ + yW-4()(X,0'A, 0. The voltage across the inductor (passive sign convention) is 28 V at t = 0.
a) Find the expression for the voltage across the inductor for t > 0.
b) Find the time, greater than zero, when the power at the terminals of the inductor is zero.
A silicon abrupt junction, approximated by a step junction, has a doping of NA= 5 x1015/cm3 and ND= 1015/cm3 and a cross-sectional area (A) of 10-4cm2. Assume the depletion approximation, VA=0, and ni=1010/cm3 to: a. Calculate Vbi.
A circuit is required in order to control a network of switches. The circuit has four inputs: three of the switches are normal on/off switches while the fourth switch is an enable switch for the entire circuit. The circuit should have the followin..
The design must show all stages used in its development and must be implemented and tested in PSpice and suitable timing waveforms produced.
Shuffle a deck of cards and pick two cards at random. Observe the sequence of the two cards in the order in which they were chosen. (a) How many outcomes are in the sample space (b) How many outcomes are in the event that the two cards are the same ..
Current to Voltage Op Amp Circuit, A 12-bit DAC (Digital to Analogue Converter) gives an output range of 0 to 1 mA for a digital input word of 0 to 4095
You are designing a 2.4 GHz receiver with a 140 MHz IF. System design constraints require that the local oscillator power be minimized to reduce the potential for interference to other systems as well as to reduce the receiver power consumption.
Design the combinational 3 bit gray to binary code converter for conversion angular position of a shaft into binary code. 1) Complete the truth table 2)obtain the minimal solution with a K map 3) draw the circuit diagram, labels the inputs and output..
Expand the memory unit to a 32x4 RAM using two 7489ICs ( you might use the HM6116A120 chip for the Multisim Program Simualtion). Use the CS inputs to select between the two ICs. Note that since the data outputs are 3-stated
Isc of 3.3A under input power Pinput=1kW/m^2. Assuming diffusion dominated behavior and no parasitic resistance elements, what is the device conversion efficiency at the maximum power point
Write a control algoirthm for a temperature control loop for a heat echanger (steam to hot water) employing a temperature control valve, controller, and thermostat. In your algorithm include a step change and ramp change.
A radio link receiver has a signal sensitivity of 100 milliwatt. The SNR required is at least 14 dB. Which is the maximum noise allowed in the receiver.
Suppose that we define the value of the complex constant A as A = -2 + 2j. Write the constant A in magnitude-angle form, that is, find |A| and A such that A = |A|ej A Sketch the real part of the function z(t), where z(t) = Aej(500pit+pi/2).
