In Johns and Martins 'Analog IC Design' book, page 222 Basic Opamp Design and compensation, the authors said that reasonable sizes for the length of the transistor might be somewhere between 1.5 and 2 times the minimum transistor length available of a particular technology.
Is this 1.5 ~ 2 times minimum length a rule of thumb in practical design? What's the reason for that? I thought one should select smallest length if possible to reduce capacitance thus minimize power..
any hints?
