there are basically two ways to do it: one is in layout, use multi-finger, and the other is in design by maximizing the overdriven voltage of both MOSFET need to be matched

Weak and moderate inversion level is optimal region for amplifier. Strong inversion for diff pair is used in Gm-C filter where linearity in attention.

Jitter, Noise, and Signal Integrity at High Speed, is a basic and high-level introduction to terminology, definitions, and concepts concerning jitter, noise, signal integrity, bit error rate, and working mechanisms for communication link systems

EDA tools can assess the first-order jitter and other performance attributes of the phase-lock loop, a critical block in many systems
