a current entering the upper terminal of an ideal basic circuit is i= 20cos 5000t A. Assume the charge at the upper terminal is zero at the instant the current is passing through it maximum value. Find the expression for q(t).
(a) Find Cox and (b) For an NMOS transistor with W/L = 15 m/0.25 m, calculate the values of VOV , VGS, and VDSmin needed to operate the transistor in the saturation region with a dc current ID= 0.8mA.
AC source Voltage in series with R1(4 ohm) and then R2(1 ohm). Vs=9sin(2t +13degrees) find the instantaneous power deliverd to R2 (1ohm) at t=0,t=1,t=2
Find the longest allowable evaluate time if the decay in output voltage is to be limited to .2V. If the precharge interval is much shorter then the maximum allowable evaluate time, find the minimum clocking frequency required.
A shunt regulator utilizing a zener diode is biased on through a 100-ohm resistor. Determine the change in the regulated output voltage for the two situations below a) VI changes +2.0 V, ILoad constant b) ILoad changes +100 mA, VI constant
An Electrical System is rated 10kVA, 200V at a .5 leading the power factor. a. determine the impedance of the system in rectangular coordinates. b. find the average power delivered to the system
Sometimes audio (or any) signals x(t) are decomposed into a sum of sinusoids. Consider x(t) the sum of three sinusoids of frequencies 518Hz, 730Hz, and 524Hz whose amplitudes are 1/2 of their corresponding frequencies.
The bottom of the conduction band at one end of a silicon resistor is at the same energy level as the top of the valence band at the other end. What current flows through the resistor if the resistance is 1.12 kOhms
A 50 ohms lossless transmission line is to be connected to a load of 25 ohm. Use a lamda/4(quarterLamda) length of line of unknown impedance between the load and the 50-ohm line to match it,
The signal x(t) = 20*sinc2(400t) is input to a ring moodulator. Sketch the spectrum of vout and find the range of values of fc that can be used to transmit this signal.
The contects of a six-bit register are initially 100101. The register is shifted four times to the right, with the serial input being 1101. What are the contents of the register after each shift
Convert the following to hexadecimal 1600 sub script 10 2. compute the sum of the following pairs of signed 6-bits binary numbers. In parallel, show the operands and the answer in decimal. Indicate if or if not an overflow occurs.
