What is the relationship between the threshold voltage and the device's noise performance, particularly in terms of flicker noise and thermal noise?

The threshold voltage (Vth) of a MOS device plays a crucial role for its operation. At the same time, noise is an intrinsic factor. So how noise (flicker or thermal) change with the change in...
