We wish to generate two currents equal to 50 μA and 230μA from a reference of 130μA. Design an npn current mirror for this purpose. Neglect the base curents.
Use a capacitor, a resistor and an operational amplifier circuit to design an active first order low pass filter which passes frequencies that human can hear (below 15kHz). Show all the calculations required to find the values of all the passive comp..
1)A passive high-pass filter is built from a 100 kohm resistor and a 100 nF capacitor. what is its cutoff frequency 2)For the filter in the above question what is its numeric gain at its cutoff frequency
What is the principle behind CRT(CATHODE RAY OSCILLOSCOPE), and How this method is simplified in LCD and LED. Is the same CRT principle used in LCD and LED Televisions. If no what is the principle used in LCD and LED Tvs.
The input impedance of a 31cm long lossless transmission line of unknown characteristic impedance was measured at 1 MHz. With the line terminated in a short circuit, the measurement yielded an input impedance equivalent
The energy stored in a 2H inductor is 400J and is decreasing at 200J/s at t=4 seconds. Determine the voltage magnitude and curent magnitude at t=4 seconds. Does the current enter or leave the positive terminal of the inductor.
Listen to both versions of "Tutti Frutti" by Little Richard and Pat Boone. Then compare and contrast the songs and describe the styles and characteristics of each song. In addition, connect them with themes of the Blues and Rock n Roll.
A p-channel JFET operating at VSG = 0 is connected in series with a power supply V and a resistor R = 10 k. Ithas been found that for V 12 V the voltage across R is constant at 10 V. What are IDSS and VP for this FET
A core with three legs is shown in Figure P1-5. Its depth is 5 cm, and there are 200 turns on the leftmost leg. The relative permeability of the core can be assumed to be 1500 and constant. What flux exists in each of the three legs of the core..
From a simple pn junction diode, predict the expected relative magnitudes of ac capacitances in a bipolar junction transistor under normal operating conditions(base emitter junction forward biased and base collector junction reverse biased).
Wires manufactured for use in a computer system are specified to hve resistances between .12 and .14 ohms. The actual measured resistances of the wires produced by company A have a normal probability distribution with mean .11 ohm
Design a RC phase shift oscillator that makes a pure sine wave (no clipping or other distortions) at a frequency of 10 kHz. Output voltage should be 9 V pp. Design a differential amplifier with Icq = 0.5 mA in each BJT and Difference mode gain = 40..
