Explain how a p- n junction diode may be used to detect optical radiation. Distinguish between the photoconductive and photovoltaic modes of operation.
A photodiode is to be used, without applied reverse bias, to detect optical radiation with vacuum wavelength 0.8 μm and incident powers in the range 10 μW to 1 m W. The photodiode has a 70% quantum efficiency and a dark reverse saturation current of 1 nA.
Calculate the value of the load resistance needed to ensure shot noise limited detection at room temperature. Why cannot linear operation be achieved if the photo detector is directly connected to this load? Explain how a transimpedance amplifier may be used to overcome this problem.
A three-phase 60-Hz induction motor runs at 715 r/min at no load and at 670 r/min at full load. How many poles does this motor have?
Important information about Electrical Networks, Engine consumes 5kw of power and a reactive power of 2kvar at current of (3+j2) Amps.
In addition, the stopbandattenuation is to be at least 65 dB, starting at the Nyquistfrequency of 22.05 kHz. The complexity of the filter shouldbe minimized. Sketch the filter specification (amplitude vs.frequency). Which filter family would you e..
The operational amplifier below has a specified input-bias current IIBup to 250nA and a maximal input-offset voltage VOS of ±3mV. It has a unity-gain frequency (gain-bandwidth product) of 1MHz.
design an alarm clock using VHDL and implement in FPGA (Basys2 Board). the scope is that, when the time and alarm time are equal, then alarm rings. A sign or some kind of indication will be shown on a LCD monitor.
2. What is the sampling period 3. What is the bit time 4. What is the bit rate of that system 5. What is the time allotted to each channel
Determine the lower critical frequeircy and label this poirrt otl your graph. Determine the upper critical frequency and label this point on your graph.
Assume that two antennas are half-wave dipoles and each has adirective gain of 3 db.If the transmitted power is 1 w and the two antennas are separated by a distance of 10 km,what is the received power
The binary-coded-decimal (BCD) format uses 4 bits to represent 10 decimal digits. For example, 259 in base 10 is repesented as "010 0101 101" in BCD format. A BCD incrementor adds 1 to a number in BCD format.
