a.Assume an NMOS transistor is operating in the Saturation region and that it was observed that the drain current increases by 25uA when the drain voltage is increased by 250 mV. Explain why? b.The Thrristor is a bipolar device, yet can be damaging in a Bulk-CMOS technology. State why?
a. design a half-subtractor circuit with inputs x and y and outputs Diff and B out. the circuit subracts the bits x - y and places thedifference in Diff and the borrow in B out. b. design a full- subtractor circuit with three inputs x,y,B in andtwo..
Design a synchronous circuit that implements a 4-bit decade (modulo-10) counter (0000,0001, ..., 1001, 0000,...) a. Fill in a transition table (using don't cares for undefined next states).
1-mH inductor carries a current: i(t)=50*t^2*exp(-2*t) inunit of mA. Determine the voltage, power, and energy of the inductor as a function of time.
A somewhat discharged automotive battery has an open-curcuit voltage of 12.5 V and supplies 50 A when a 0.1 ohm resistance is connected across the battery terminals.
Design a square wave oscillator using an (ideal) operational amplifier. Verify your design with Spice-like software waveform. Specifications: peak value: ±5 V, frequency: 1000Hz, duty cycle: 50%.
Three single-phase transformer are used to form a three-phase transformer bank rated 13.8kV(delta)/120kV(wye). One side is connected to a three-phase load of 12 MVA at 0.8 power factor lagging. Determine the turns ratio of each transformer
v(t)=20te^( -40t ) and i(t)=50te^( -40t ) for t>=0 both v and i are zeros for i
find the desired recycle ratio (moles recycled/moles fresh feed) if in the fresh feed A is 20% in excess, the once through conversion of B is 60%, and the overall conversion of B to products from the overall process is 90%.
Consider a source-free parallel RLC circuit having alpha =10^8 s^-1, omega-sub-zero = 10^3 rad/s, and omega-sub-zero * L = 5 ohm. a) Show that the stated units of omega-sub-zero * L are correct. b) Compute s_1and s_2.
purchase an inductor coil for a resonance circuit resonating at 1500 kHz; the operating bandwidth is 10 kHz. What is the quality factor Q of the coil
The shaft output of a three-phase 60- Hz induction motor is 80 KW. The friction and windage losses are 920 W, the stator core loss is 4300 W and the stator copper loss is 2690 W. The rotor current and rotor resistance referred to stator are respec..
