Op Amps: Gain Bandwidth Product

Показать описание
In this video we investigate small signal frequency response; specifically f2, the upper break frequency. This is determined by the op amp's gain-bandwith product or f(unity).

I was 1 minute in when the first question popped into my head. In VHF applications, is it possible to, somehow, lower the frequency to fit within the bandwidth of the circuit elements and then raise the frequency again later in the circuit? I can imagine a generator spinning might work and also if it's actually a problem that needed solving? Thanks for a great video, some of this was new to me.
