Are there many analog ic design companies in Canada?
Can anyone give some links?
Is it easy to find a job for analog ic design engineer in Canada?
Thanks!
You can search for the project solutions of EECS240, which gives the design flow for different types of differential OTAs.
Also EE214 lecture give an example of differential OTA design using gm/id methodology.
In the attachment, page 7, answer d, there is gmro vs vds curve, which is just like the waveform you pasted.
With spectre simulator, I can measure ro=1/gds, gm respectively.
I do not know wheter pspice can do it or not.
You can also refer ee214 lecture which give some spice netlist for...
I use Cadence composer to draw schematic, Virtuoso to draw layout, spectre and spectremdl to run simulation.
Change the testbench in EE214 to spectre format, record the gmoverid, ids, etc ,and can easily get the waveform just like in the paper.
1)Edit "gmid_nmos_ee214.scs"
//NMOS gm/id...
Hi, EmbdASIC,
In EE214, gm/id simulation test bench is in the attachment.
Also, in EECS240, gm/id simulation test up is using a diode connected NMOS and sweeping the Vds.
You can try both.
Best Regards
Hi DenisMark,
Have you ever simulated open-loop gain vs vod, AC loop gain @Vod=0 and AC loop gain @vod=vod,max which were described in EE240 project?
How to add the stimulus?
Best Regards.
