I'm trying to understand the proper biasing procedure of a cascode distributed amplifier part that requires three power supplies. A positive drain-source VDD, a negative gate-source VGG1, and a second, positive gate-source VGG2.
The recommended biasing procedure is for the bottom MESFET VGG1 to be supplied, then the drain-source VDD, and finally the top MESFET VGG2.
I don't know much about amplifier operation, I was tasked to document the proper biasing procedure for parts and determine if there will be an issue. Case in point the VGG2 may be supplied by a linear regulator that's always on while VGG1 and VDD will be controllable. I want to understand what the ramifications of having VGG2 always being on
***EXTRA: I could also use help in trying to model the situation in ADS to have a visual representation of the problem.
