Hi,
I am using an Apex PA443DF operational amplifier to drive a sinusoidal signal at 100 V amplitude across a very large resistor with resistance of about 5000 Mega ohms. The amplifiers are set up as noninverting with a gain of 22 and function very well for small resistive loads. The sinusoids...
1. Using the frequency equation I know the time period is 1 millisecond.
2. The duty cycle (50%) equation tells me that the pulse width and the amplitude is 1 V.
3. Thus the input waveform looks like this : (?)
4. As the slew rate is 0.5 volts per microsecond, the output voltage would take...
Here I let ##R_2 = 2 ## kohms and ##R_1 = 1## kohms. Using this suggests that ##R_3 = 0## and ## R_4 = 1 ## kohms (?!)
The resulting circuit is
Is this the correct way to solve this?
PS : I just realised that I have interchanged ##V_1## and ## V_2## in the diagram!
The open loop voltage gain is given as :
$$ u(s) = \frac{u_o}{1+\frac{s}{w_o}} = \frac{100}{1 + \frac{s}{40}}$$
Where u_o is the d.c. voltage gain and w_o is the pole.
The op amp that is given is:
And I am told to use the non ideal op amp model as follows:
Well my guess is that I can...
Homework Statement
The op amp has a near ideal level 1 model with G = 5000V/V, ri = inf, ro = 0
How would I obtain the feedback function?
Homework Equations
I know I have to find the feedback function which is:
f = - (ΔV/Vin)
The Attempt at a Solution
I will first drive using the...
Homework Statement
Derive the expressions for the voltage gain (Gv) of the following op amp:
Homework Equations
In = Ip = 0
Vp =Vn
The Attempt at a Solution
I can use KCL, and the fact that In and Ip are both 0, to derive the two equations, one from the top node and the other from...
Homework Statement
The opAmp network shown in figure 68 is a transimpedance amplifer that employs both negative and positive feedback. Assuming that the op-amp is ideal, calculate the value for the output voltage for Jg is 1mA.
The circuit and question are this...

CMRR = Av/Acm
Acm= Δ/R , Δ = (2 x Tolerance of Resistor).R
The Attempt at a Solution
I have to admit I am a bit confused by the premise of the problem.
My understanding is Vout is used to vary Vcharge in some way, so that Icharge is always 1.3 A. Then...
