The output stage of an amplifier in an old radio is to be matched to the impedance of a speaker. If the impedance of thespeaker is 8 ohms and the amplifier requires a load impedance of3.2 kilo ohms, determine the turns ratio of the ideal transformer.
An IC NMOS transistor has W=100μm, L = 10μm,μnCox= 20μA/V2, VA= 100 V, γ = 1/2 V1/2, Vt0= 1V, and 2φf= 0.6V. calculate the value of Vt at VSB= 4V. Also for VGS=3V and VDS=5V, Calculate ID for VSD = 0V and for VSB = 4V
Although this forms PNP and NPN transistors, the bias of the regions is designed so the junctions are reverse biased and the electric field effects on the channel are supposed to control the MOS-FET transistor soperations.
The input power is 0.78 watts. The efficiency of the amplifier must be at least 61%. What must the gain of the amplifier be, how much power is at the output, and how much power is dissipated
Calculate the received power and the path loss. Assuming this is the maximum acceptable path loss for the system, how does the maximum system range change at 1 GHz and 10 GHz, assuming all other parameters remain constant
Why is V2 and the 2kO resistor included in the KCL equation at node V1. Similarly, why is V1 and the 3kO resistor included in the KCL equation at node V2.
An air-standard Otto cycle has a compression ration of 9. At the beggining of compression, p1=100 kPa and T1= 300K. The heat addition per unit mass of air is 1350kJ/Kg. Determine. a) the net work, in kJ of air. b) the thermal efficiency of the cyc..
A circuit is required in order to control a network of switches. The circuit has four inputs: three of the switches are normal on/off switches while the fourth switch is an enable switch for the entire circuit. The circuit should have the followin..
John's house is served electrically by a single phase transformer rated 15 kVA, 8160 / 220 V, 60 Hz. The leakage reactance of the transformer is 400 ohms referred to the high side. John wants to replicate an interesting EEE 360 experiment
