An NMOS differential amplifier employing equal drain resistors, RD = 47 Kohms, has a differential gain Ad of 20 V/V.a) What is the value of gm for each of the 2 transistors?b) If each of the 2 transistors is operating at an overdrive voltage VOV = 0.2 V, what must the value of I be?c) For vid = 0, what is the dc voltage across each RD?d) If vid is 20-mV peak-to-peak sine wave applied in a balanced manner but superimposed on VCM = 0.5 V, what is the value that VDD must have to ensure saturation-mode operation for Q1 and Q2 at all times? Assume Vt = 0.5 V.
A double-A (AA) rechargeable battery is rated at 1.2V, 2100mA-h ( mili-amp hours) 1- how many coulombs of charge can this battery hold 2- how many joules of energy are stored in the battery
When the input x(t) = 5u(t) is applied to a linear second-order circuit the response of the state variable is y(t) = 10e^(-100t)-5e^(-200t) + 5. Design a simple RLC circuit that would produce all of these responses.
Suppose that the cost of electrical energy is $0.12 per kilowatt hour and that your electric bill for 30 days is $60 (power usage only, not including other charges or taxes) Assume that the power delivered is constant over the entire 30 days.
A synchronous sequential machine having a single input x and a single output z is to be designed. The output z is to become 1 upon completion of the input sequence 0101, whether it forms part of an overlapping string
A voltage source V(t)=100cos(6Π109t - 45(degrees))(V) is connected to a series RLC circuit. If R = 10MΩ, C = 100pF, and L = 1H, use phasor notation to find the following: a.) i(t) b.) Vc(t) (voltage across capacitor)
The question considers the design of a 8x1 multiplexer using gates. Assume the data inputs are I0,...,I7 and the select inputs are S2, S1 and S0. (a) Write a sum-of-products expression for the 8x1 multiplexer.
The ABCD constants of a three-phase, 345-kV transmission line are A = D = 0:98182 + j0:0012447. The line delivers 400 MVA at 0.8 lagging power factor at 345 kV. Determine the sending end quantities, voltage regulation, and transmission efficiency.
