Thermal Noise for a MOSFET transistor 4KT u * Inversion Current/L^2. In saturation region comes out to be 8KTGm/3 and flicker noise is K/Cox*WL*f. So by making a larger transistor we reduce the flicker noise and having a larger value of L we reduce thermal noise. There exists a trade off between flicker and thermal noise up to some extent.

You have three adjacent parallel metal lines. Two out of phase signals pass through the outer two metal lines. Draw the waveforms in the centre metal line due to interference. Now, draw the signals if the signals in outer metal lines are in phase with each other
