Common centriod technique is not limited to current mirrors or differential pair circuits. One can split a large transistor into possible equal parts and use this technique.
One can help if you provide a snap shot of your circuit. It also depends on individual, which group of transistors he/she...
Common centriod is one of the layout strategies to mitigate the effect of parasitics.
This technique helps in cancelling the effect of parasitics.
Consider this example: If we have no. of negatives equal to no. of positives, overall effect will be null.
Similarly if you can allign transistors...
One way is to use the concept of ICMR , & the other procedure is by using the tool (cadence)
Following are the steps for doing that :
1. Make a gedit file with name "saveops.scs" and mention different transistors M1, M2, M3 etc in that file with
the syntax,
SAVE OPPOINT MX;
where X is...
Dear Sir,
i checked this, but still not working...ok
I tried to workout a simple inverter..but it the above mentioned error is still coming...I am attaching screenshot of layout ...
Please look into it..
Thanks!!!
While doing LVS for my circuit I am getting following errors....Can anyone tell me what are these???
1. ptap must be connected because of same Net/diffNet
2. 'nsd' must be connected because of sameNet/diffNet
Thanks!!!
Differential phase shift keying is a non coherent form of phase shift keying which avoids the need for a coherent reference signal at the receiver. Further PSK needs coherent detection due to its phase shift with a refrence signal. you should keep in mind that no coherent receivers are easy and...
