Find VDSQ and IDQ for the FET shown in Figure, given Vto = 3 V and K = 0.5 mA/V2. Find the value of gm at the operating point. Draw the small-signal equivalent circuit, assuming that rd =∞. Derive an expression for the resistance Ro in terms of RD and gm. Evaluate the expression for the values given.
The system works as follows. When the main program starts to run, the microprocessor commands the A/D to convert. The microprocessor then sits in a dummy loop until the A/D interrupts, after it has completed the conversion and data is available.
Analysis of z transform to time domain, poles and zeros, From a given z transform X(z) = {1- z^-10}/{1 - z^-1} the discrete time domain form x(n) is deduced using complex manipulation and inverse transforms to arrive at x(n) = x(n-1) + u(n) - u(n-..
Determine the transform for g(t) = rect(10t)cos(400 Π t). Use the table of transforms and the convolution property of the impulse function.
A 3-bit binary counter can be implemented with 3 T-flip-flops and some additional logic. Design the counter. Draw the block diagram (gates) and show the Boolean logic the input into each Flip-flop.
Submit an excel spreadsheet with your characterization results, and a screen shot of you amplifier schematics, and your simulation result running a sin wave (Use a vsin for input).
A transducer produces a sinusoidal waveform with an amplitude of 2.5 VPK and a DC offset of 0 VDC. The ADC input signal range is 0 V to 5 V. Describe the signal conditioning circuit that is needed to use the full-scale range of the ADC.
a 10kW 220 V single phase ac motor is operating at .7 lagging power factor. Find the value of the capacitor that needs to be connected in parallel with the motor, if the power factor is to be improved to .95 lagging
Suppose that we are designing a cardiac pacemaker circuit. The circuit is required to deliver pulses of 1-ms durstion to the heartthat can be modeled as a 500-Ω resistance. The peak amplitudeof the pulses is required to be 5 V.
