    Errors in the Layout after DRC

    Hi, I am using MOSIS 0.35um process. While doing the layout, after DRC i am getting the following errors. 1) LATI. 3A N-Well PICK-UP to PMOS max space < 20um 2) LATI. 3A P-Well PICK-UP to NMOS max space < 20um Can anyone help me solving these errors. Thanks in advance,

    MOSFET Characteristics

    Hi, I would to know the effect of (W/L) on the transistor characteristics. i.e., even though if we keep the ratio same, how would different (W/L)s effect the shape of the transfer curves of the MOSFET. Ex: (6/2) , (12/4), (24/8) etc. In all these examples the ratio is 3 but the...

    howtotest if amplifier has PM 70 degree

    connect one of the input to some dc voltage....then connect the other input to an ac source with the same dc bias and give it a little swing... For example: fix Vin+=1.5V Vin-=0.1V swing with dc bias of 1.5V now you get the output plot the magnitude and phase response.... now observe the...
