Okay I will look into it, thanks!

To be honest nowhere, this is a task I was given for my bachelor thesis.

For the C; I first tried finding the transfer function without the push pull stage and since the caps are "hanging" at the output of the push pull stage I neglected them. Now for the circuit itself; (I find it cool you remember my earlier post). I actually never crossed the mirror currents...

Hello; (this is going to be lengthy post) So im trying to find the small signal differential gain of this circuit The input is at the 2 NMOS's above the degeneration resistor and the output is where the capacitors are hanging (excuse that I didnt label them, the program where I drew the...

Sorry it took me so long to get back to this, but I have solved my issue. The answer was a diffrential resistor at the output (Iop and Ion) such that it matches my degeneration resistor. The current without the degeneration resistor is exactly what I expect it (Ibias) and with the degenration...

I will talk to my professor about this; but to answer at least one of your question; that link that is cropped off is just where I should download the docker that contains Xschem, has nothing to do with the actual task I will get back to you after I ask my professor. Thanks!

So remove the CMFB and just place loads on the Gm2 as it is (with P-P stage)? I did that; in the following way; so this is how the circuit looks like now What I changed are the value for the load I made them to match Gm = 1/Rs and I also made the transistor values in my Gm cell such that M18...

Okay I kind of did that. If you look at the circuit I posted in #4, I first built and tested the differential pair with the diode connected PMOS loads, without the Push Pull stage. I loaded the circuit such that Rload matched my Gm,where Gm is 1/Rs and the circuit works as intended (if you would...

Okay that helped kind of; my current i(vop) the one i have posted in #1 is still in nA but its shape resembles a lot more what I am looking for and its going from 0 to 16nA which is the behaviour I am looking for (for it to start at 0 and then rise) I think I left something important out tho...

Hello; just for reference here is the circuit I am building NOTE: the bottom 2 transistors on the far left and right (The push pull stage) are susposed to be NMOS here they are PMOS but they are susposed to be NMOS and I have built them in as NMOS; Now I have the left side of this circuit as...

Hello; I am trying to build a Gm cell using a degenerated differential pair; I also have a Common Feedback Circuit so that I can keep the output at Vdd/2; This is how my Gm Cell looks like Basically I have M1 and M2 Nmos and i feed it a differential voltage, the bottom transistors are a part...

Hello! Consider this transfer function $$ G^\#(q) = q \cdot \frac{q^2 + 2q - 3}{q^2 - 25} $$ a) For which values of Ta > 0 is the G(q) step response capable? b) For which values of Ta > 0 is the G(q) realizible? c) Is it possible to find a sampling time Ta > 0 so that the G(q) is BIBO stable...

TL;DR Summary: Writing functions for Bisection and Newtons Approximation in Mathematica Hello! I need to write 2 functions in mathematica, to find the roots of functions. The functions are the Bisection methods and Newtons Approximation. (b1) Write your own function ApproxBisect[a0_,b0_,n_]...

I think I will try it like this; What is the equation that relates the components of the normalized IEEE-754 single-precision representation to the value it represents: $$ v \; = \; \left( -1 \right)^S \left( 1 \; + \; \frac{M}{2^{23}} \right) 2^{\left( E-127\right)} $$ Now I define ## v_1 =...

Hm okay interesting so you would bet on 2^(-23) to be the answer? Considering that ## 1+\epsilon > 1 ## yields the same answer can we state that the minimum value is always ## 2^{-23} ## regardless what teh constant factors are ?
