People in the microwave/RF field constantly talk about how it is "difficult" to match a high-Q circuit (ie. a CS amp with very little gate resistance and no degeneration). Why is that?
The problem is made slightly more confusing for me by the multiple quality factor definitions. If I consider the fractional bandwidth definition, it kind of makes sense that a circuit having a very narrow bandwidth would be more adversely affected by the addition of any parasitics. Thus tuning a matching network to resonate at such a narrow frequency might prove tricky. Am I going in the right direction with this?
