Same rules apply -- what is the bandwidth in question? What is change, and rate of change, of Icc/Iee? What is tolerable change in Vcc/Vee?
Supply pins of analog elements tend to be more reactive than digital, in that digital ICs have considerable on-board supply capacitance (whether by sheer number of transistors/junctions, or explicitly as capacitors piggybacked or on the interposer), with a consequence for example, that you can do tricks like the old "float an op-amp between two BJT bases to increase output voltage and current range", with obvious potential downsides such as unexpected CM/DM oscillation modes, or more generally speaking, poorly or un-documented supply port responses. Not that this probably matters at high frequencies, where you wouldn't expect such tricks to work anyway, or not very well, but the flip side of that is, we need to provide suitable supply port impedances, whether that's simply by way of being low enough, or by being unreactive (a higher impedance might be acceptable, as long as it's well damped?).
Amps aren't usually documented in terms of supply port embedding impedances, unfortunately. At least, none that I've seen, but I haven't exactly looked at a lot of high speed types myself.
It shouldn't be any different than digital PDNs, other than frequency of interest and impedance spec required. E.g. if an amplifier has BW of 10MHz, then it should be sufficient to optimize PDN not much beyond that. On the other hand, if your amp has bad PSRR and you need a solid supply that doesn't move as the amp consumes current, then the impedance required might be lower than what an FPGA has to deal with.
Yeah, with the catch that, somewhere above 10MHz for such an amp, there might be rectification effects. It probably goes without saying,
not to microwave your analog circuits via PDN-transmitted RF, but, just for completeness sake.
Note that, if PSRR is bad, and the supply has long time constants, then you will read those time constants as secondary error in the output; this may be important for precision and fast-settling applications. It might well be preferable to use a modest impedance source, but ballasted to be very stable (resistive), to convert this into a flat gain error rather than numerous time constants.
Which I suppose might be a point in favor of zener shunt regulation, Ri being quite small and zener/avalanche effect acting very quickly, and with proper choice of diode (i.e. ~6.2V or stacks thereof), thermal error can be minimized as well. Since any kind of active regulator necessarily has output time constants corresponding to loop response.
But then, PSRR varies with frequency too (usually proportional to amp gain itself), so this probably doesn't mean much. It should be easy enough, at least, to choose an amp without quite such poor PSRR that such extremes become necessary.
