Basic Precautions for an Analog Designer — by Ajay Kumar

Basic precautions and tips that an Analog Designer should know.

1. Minimum channel length of the transistor should be four to five times the minimum feature size of the process. We do it, to make the lambda of the transistor low i.e. the rate of change of Id w.r.t to Vds is low.

2. Present art of analog design still uses the transistor in the saturation region. So one should always keep Vgs of the Transistor 30% above the Vt.

3. One should always split the big transistor into small transistors having width or length feature size < or = 15um.
