(a) A CMOS inverter is biased at VDD = 2.5 V. The transistor parameters are Kn = Kp = 120μA/V2, VTN = 0.4 V, and VTP = -0.4 V. Calculate and plot the current in the transistors as a function of the input voltage for 0 ≤ vI ≤ 2.5 V.
(b) Repeat part (a) for VDD = 1.8 V and 0 ≤ vI ≤ 1.8 V.
(1) Can we have Darlington transistor made up of an NPN and a PNP or do the two transistors have to be of the same type (2) Amplifiers has a power gain of 1,000 or 30dB. Where is that power coming from
a. Is this a synchronous or an induction motor? b. Estimate the frequency of the applied armature voltage in hertz.
A typical method of measuring the linearity of an amplifier is called the "Two-tone" test. Signals at f1 and f2 are input to the amplifier and the output spectrum is observed. Assuming that signals at 14.1 and 14.2 MHz are input to an amplifier.
Design an analog computer circuit to solve the following differential equation 1)Draw the state flow diagram 2)Design and draw the OpAmp circuit. Show the values for the resistors and capacitors. Label all inputs and outputs
Build a 1Gbps link as long as possible without regeneration. Assume a transmitter power of 1mW and a receiver sensitivity of -30dBm for a BER of 10^(-9). The dispersion at 1.5 micron is 20 ps/km.nm, and the attenuation is 0.25 dB/km.
in a p+-n junction, the n side has a donor concentration of 10^16 cm^-3. if ni=10^10cm^-3, the relative dielectric constant εr = 12, dn=50cm^2/s, Dp = 20cm^2/s, and the electron and hole minority carriers have lifetimes τ=100ns
Draw a Nyquist plot of G(s) and examine the stability of the closed-loop system.
Show that the sum of any two forward time-like vectors is itself forward time-like, and hence that the sum of any number of forward time-like vectors is its self forward time-like.
A novel design for a condenser consists of a tube of thermal conductivity 200W/m · K with longitudinal fins snugly fitted into a larger tube. Condensing refrigerant at 45°C flows axially through the inner tube, while water at a flow rate of 0.012 ..
An 8 bit unipolar Successive Approximation Register type ADC is used to convert 3.5V to digital equal output. The reference voltage is +5V - The output of ADC at end of 3rd clock pulse after the start of conversion
The pre- Limiter circuitry has a Noise Figure of 8dB and an input Noise Temperature of 1800C. Given an FM demodulation noise improvement of 17dB, determine the minimum receive signal power to achieve a post detection signal to noise ratio of 35dB.
