In case that Vgg1 is pre-adjusted and fixed by register divider, is following sequence no problem?
The biasing sequence:A) Set Vgg1 (Idq adjusted voltage, fixed to somewhere between -2V and 0V)B) Set Vdd to +8VC) Set Vgg2 to +3VTiming: A)<B)=<C)
My customer understands recommended biasing sequence described in https://ez.analog.com/docs/DOC-11963, however, from circuit size point of view they would like to apply fixed voltage to Vgg1 by resister divider.
Thanks for your answer.Is the inquired biasing sequence applicable to all non-self-biased HMC amplifiers that have Vgg1 and Vgg2? Or is it applicable to specific non-self-biased HMC amplifiers? I would like to known it for supporting other HMC amps and future opportunities.
