A silicon varactor diode exhibits a capacitance of 200 pF at zero bias. If it is in parallel with a 60-pF capacitor and 200-A????1H inductor, calculate the range of resonant frequency as the diode varies through a reverse bias of 3-15 V. ( 966kHz, 1.15MHz)
Design a square wave generator that will provide a 4kHz square wave with a positive peak vlaue of +10V and negative peak value of -10V. You may use any number of op amps, resistors, and capacitors in this design.
The surface concentration is fixed at N0=1.8e20/cm^2 when diffusing boron into a uniformly doped n-type substrate. The atomic diffusion constant for boron in Si at the temperature of 950 C is 3.0e-15 cm^2/s.
the atomic weight of sodium is 23 and the density is 0.97*103 kg/m3. calculate the number of electrons in a cubic meter of sodium.
Typically, a speech signal that can be understood over a telephone shows frequencies from about 100 Hz to about 5 KHz. What would the sampling frequency fs (samples/ sec) that would be used to sample a speech without aliasing
The circuit arrangements for each of the installations, the final circuit cable selection, the maximum demand estimation, and the circuit protection arrangements should be designed.
Inflation in years 1-5 equals 3.1 percent, 2.2 percent, 1.6 percent, 1.3 percent, and 1.1 percent, respectively.

Write a 4-bit up counter. Your counter has a asynchronous clear and when the clear is activated, the counter is reset to 3. The count range is from 3 to 9.
At the end, the wave totally reflects with a pi phase shift, and the reflected wave now interferes with the incident wave to yield a standing wave pattern over the line length.a) Determine the standing wave pattern for the voltage in the line.
Draw a circuit of a mulitplier using only combinational circuits. Construct your multiplier for X*Y, where X and Y both are2 bit binary numbers
