Thanks.
The hysteresis is internal. I have ran transient and getting strange results. Would like to run DC sweep saving hysteresis point (option in dc simulation).
Now forgetting about all the second order effects the question is basically the one I did above. Because in transient I am...
Hi all. Imagine you have a comparator with hysteresis and you want to determine how much trim you need.
You do MC sim.
Now if you simulate using DC simulation sweeping the input of the comparator, how would like to know the following:
We sweep up and determine the value by taking the input when...
Hi all. I would like to know if someone could enlight me how to check or how to assess/what criteria do you use and what to target for when sizing the MOSFET, via the op point information (vgs, vds, vdsat, vth, etc)?
For example:
Vgs>Vth
Vds>Vdsat (but for example by how much?
Anything else...
Hi all, for those of you that are more experienced, what's your design flow? What's your approach when it comes to design from the spec till the delivery of the block? Would like to learn from you what is your flow so that I can improve mine. If you have any examples would be nice where you can...
Hi all,
I have simulated a comparator. Before the comparator trips where it should it trips a bit earlier with no apparent reason. I am using gear2only and tried traponly and when using the trapownly I don't see this strange behaviour. Basically I am sweeping the input of the comparator very...
Thanks for the links. But what I am trying todo is using the cadence function DNL and INL to calculate this from a DC simulations (using the DC step).
Does anyone know how to do this? There a delay thing that doesn't make sense for DC. Then a step.
Thanks for your comment. Appreciate it.
Basically it applies to any circuit I think. Current mirrors, amplifiers, iDACs, namdgap circuits, etc.
How do we access the transistor operating point? What is, as a rule of thum - of course will depend on the type of circuit, but as a rule of thumb how...
Hi all. Noob here. How do you check a transistor for the operation point and what are the best values to look for? Someone told me things like your vds>vdsat and all that but didn't understand why.
What are the criteria to check the different points of operation of a transistor using its...
