I couldn't find out what would be the gain for this given circuit given the open loop gain of
This is my guess
I can find that the loop gain Aβ is equal to gmRd which

for series...the current remains unchanged as tat of the input ...and voltage is added or subtracted...
for shunt ...the voltage remains unchaged as tat of the input ...and current gets added or subtracted..
same thing applies to the output
see some basic books...like..
Millman and halkais ,etc

it is used to prevent the occurence of metastable state in the inverters by the usage of feedback... also it increases the current sourcing ability of the buffer and decreasing the output impedance...

I don't like this terminology at all, because - for my opinion - it is confusing.
And according to my experience, it is used in different ways.
Some authors use these words based on the sequence input-output and some vice versa.
Based on the input-output sequence, the phrase series-shunt feedback means, that the feedback signal is

*When the feedback signal is derived from an output voltage (current) it is voltage- (current-) driven feedback.
*When the feedback signal is added to the input voltage (current) it is a voltage (current) feedback.
*Example 1: opamp as a non-inv. (...)

First of all I am right in saying the network formed by R1, Rf and Cf is the feedback network and can you pls explain why its is a voltage feedback.
During formulation of an answer I have detected an error in my first response. Sorry - it is voltage-controlled current feedback (sometimes called (...)

Hi - I'm in troble - i have to design a current sink which should load a resistor with a resistance of 0,1R.
the resistor is connected to gnd.
The current sink should be variable from 0A to 6A.
I try to design a circuit but if i test this in Pspice i get the result that this chircuit will swing.
As Variable Resistance i used a p-depletion

Does anyone have any comprehensive material for finding loop gain using breaking the loop method.
Actually I am trying to find the loop gain, phase and stability of a Transimpedance amplifier (input current - output voltage) using this method. It consist of only a single transistor with a feedback resistor from collector to base.

feedback is the method of feeding part of the output to the input to increase the gain in the case of positive feedback and increase stability with reduced gain in the case of negative feedback.....
shunt mixing and sampling and series mixing and sampling depend on the type of output and the type of (...)

The Wilson current mirror doesn't provide much advantage when using MOS. It's biggest strength is eliminating base current error when using BJT's.
However, here's how it functions in your configuration:
Assuming initially all devices are off, the following sequence of events will happen during start-up:
1) I4 will start increasing voltage

I have to design a circuit that employs negative feedback to achieve the design
specifications shown below:
Closed-Loop current Gain = 15 A/A up to 10 MHz with 60 degrees of Phase Margin
Closed-Loop Input Resistance < 1 Ohm
Closed-Loop Output Resistance > 10 MOhm
Supply voltages VDD = 2.5 V and VSS = -2.5 V

Why have to divide by 200u ?
Transimpedance = voltage/current. Your voltage output is 91mV, the current input is 200uA.

now I can't work out how or why it works..
You didn't tell which point is unclear to you. I can imagine two possible issues:
- How does said "over-the-top" mode of LT6016 work. I fear the simplified internal circuit misses some details, we simply have to believe that the specified parameters are achieved. A pnp current mirror wit

I'm not motivated to draw a circuit diagram now. I just give a few hints.
1. Consider a shunt resistor. It already is a full featured current-to-voltage converter. You didn't tell any requirements regarding input voltage drop or convertor output resistance. You can scale the resisistor to get any intended conversion factor.
2. You requested

I have an inverting amplifier and in the feedback path I have a series combination of inductor and capacitor and Resistor
Then the transfer function of the feedback part is sL + 1/sC +R.
Strictly spoken, both statements seem mutual exlusive. You would need an ideal current source to represent the said transfer (...)
