This is not a homework question,so please don't yell at me.. There is a question on my textbook..Analyze in a detailed manner the effects of the mismatch in the differential amplifier MOS.Which one has a dominating effect according to you and why? I know how to analyze the effects of the...

0.5*Io is the one in the middle,but in my exercise isn't given where is Io itself :(

Anyway,do you think that the above steps and equations are correct? :)

This is all the possible data :(

Homework Statement We have the circuit in the figure.I have to find Io. Homework Equations Mesh current analysis. The Attempt at a Solution The first mesh is i1 and the second one is i2. We have a supermesh here.Supermesh results when two meshes have a (dependent or independent)current...

Homework Statement We have the circuit in the figure.I have to find the average power consumed by all the elements and the source. Homework Equations P=0.5*(I^2)*R P=-VmImcosθ/2 The Attempt at a Solution The inductor consumes zero inductive power. I apply nodal analysis at node Vo We have...

Homework Statement We have the circuit in the figure.I have to find the current i using nodal analysis Homework Equations 1/6 F =-3j 1/2 F= -j 1/2 H= j The Attempt at a Solution So we have the equations Node V1 : [(7-V1)/(4-3j) ]=[ V1/3 ]+ [(V1-V)/-j] Node V : [(V1-V)/-j] =(V )+ (V/j) In...

Homework Statement We have the circuit in the figure.I have to find the output graphically if the input is Vi=15sinwt. Homework Equations This type of exercise doesn't have any equations The Attempt at a Solution Heres the circuit http://i.imgur.com/ivixWzH.jpg For Vi<= -10 the diode is ON...

Many thanks to both of you :) I guess finally I should write them like this? 6 +12- [v1/2] - [( v1-v)/1]=0 -2j+ [(v1-v)/1]- 12 - [ v/(-3j)]=0

Homework Statement We have the circuit in the figure.I have to find v using nodal analysis only. Homework Equations Converted 1/6 F to -3j and 2sin2t to -2j. The Attempt at a Solution In node v1 we have the equation 6= -12+ [v1/2] + [( v1-v)/1] In node v we have the equation 2j+ [(v1-v)/1]=...

Homework Statement We have Vz=6.8 V and Iz=5 mA,rz=20 Ohm,Izk=0.2 mA, R=200 Ohm and the source V= 9 volt a)Find the output voltage when we have the input voltage with the nominal value of 9 Volt. b)Find for the nominal value of the voltage,which is the maximum load current for which the...

Homework Statement We have an amplificator of low frequences like in the figure.The transistor has these h parameters: hie=1.1k Ohm,hfe=50 Ohm In the entrance we have Vs and Rs=10 kOhm. Find A1,Ais,Av,Avs,Ri,Ri',R0 and R0' Homework Equations There are many. The Attempt at a...

Nascent Oxygen,I need to have a very clear idea about what b) is like ,so I can build the transfer :)

I posted this exercise given as homework in the wrong section and it got deleted.Nevertheless,I asked my teacher to solve it and so did he.Thing is I still have some unclear stuff.Please ,a crucial part of the exercise is the part b,so please pay attention to it. Homework Statement We have the...

Homework Statement an infinite plan,parallel to the yz plan which passes from x=2 meter, is charged equally with the σ= 2μC/m^2 .A sphere with a radius 0.8 meters has its center in the in x=1 m,y=0 and has ρ=-6μC/m^3.Find the value of the intensity of the electric field in the point x=1 m and...
