THE SMART TRICK OF PIN DIODE SWITCH THAT NOBODY IS DISCUSSING

It can be LM108 and LM112 (internally compensated) and there is basically no trick there. It's 1nA enter bias which can be fairly stable with temperature as for most bipolar opamps because β really increases with temperature. Afterwards iterations like LT1008/LT1012 or OP97 pushed it down toAt an operating frequency number of 500MHz max, the isola
