Any capacitor shunts a transconductance stage results in a "feedforwad" zero at -Gm/C
M10 here is the transconductance cell but it has a -ve Gm. Hence, you have a right-half plane zero (-[-Gm/C] = Gm/C) which is the worst for stability. One of solutions is to eliminate the feedforward path as...
If you are designing an IC you can use bandgap reference circuit it can supply constant voltage and current over temperature, you can find out more about design procedure in the following book "CMOS Circuit Design Layout and Simulation, R J baker"
In discrete electronics you can find out some IC...
Sure, you must get different results, since both of "Vt" and "Is"of the BJT are functions in temperature. simulators in normal simulations run at 25 or 27 deg -depending on your simulator- , so when you set temp to 25 deg you really changed nothing in your simulation.
you can save the ocean script from your ADEXL window after naming all variables you want to plot or save, then run it from the command line in the log window using "load()" and wait until the simulation is done, then you can use "ocnPrint(some arguments)" command, google it for more help to...
First of all this topology is not a voltage amplifier, diode connection at the load causes dropping of the output impedance to 1/gm, hence gain will be around one -roughly-, but it still a current amplifier
for common mode feedback, you need it when you have two series current sources with error...
In subthreshold you can use the exponential model of the bjt where its base is coupled to the gate of the mosfet with capacitive divider, but operating in such region is not too beneficial and let me explain it more:
When you are going in weak inversion (wi) direction (subthreshold) you are...
I think you can still use simple current mirror or wide swing current mirror
the problem is that being floating results in having different source voltage from that source voltage of the mirroring mos in the reference side, so you can, in the reference side, add additional diode-connected mos in...
there are two options:
1- create simple testbench, knowing Vgs, W, and L, and Id will be calculated in the simulation, then you can substitute in the square law and find out (approx.) u.Cox
2- you can find out the equations for the model you are using, hence you can calculate the parameters you...
