Phil Hobbs is fond of cascoding two of them, afraid I forget which though. One of them has awful Early effect (or the FET equivalent), so that goes on the bottom; the other doesn't, but has awful low frequency noise, so goes on the top. Yes, the layout must be tight and usually demands a small ferrite bead on the base/gate, which must be carefully chosen since you still want some high frequencies, not just lower ones. Tim |
