Noise is the great limiter. Without it, we could communicate over arbitrarily large distances while consuming almost no power. Unfortunately for us mere mortals, we have to overcome the effects of noise in our world. In this article, we look at the sources of noise in MOS devices. You will learn:
So, reading between the lines, these modern tiny VLSI CMOS are not the nicest to use for audio or ancient radios like AM or FM? I remember discrete transistors where shot noise was a low rumble in audio range, but now you say the corner might be 100MHz, unreal.
Honestly it is hard to find the flicker noise corner in the latest and greatest nodes. While researching this article, some published papers showed flicker noise up to 1 MHz, and this was for 14nm FinFets. In speaking with some folks in industry, I was told that flicker noise corners are >10 MHz these days, could be higher. Luckily we won't need these fancy technologies for AM/FM radio :)
