- *MODS: GA DEPENDENCE INVERTED (POLARITY SWAPPED)
- * R2 INCREASED TO 7MOHM (ALL GAIN IN ONE STAGE)
- * C2 TIED TO GROUND (WAS NODE 1), REDUCED TO 3.11PF FROM 3.54PF
- * GB POLARITY REVERSED, GB=1/R02 FOR GAIN OF 1
- * RF, CF ADDED FOR CLOAD NETWORK (REDUCES VALUE OF C2)
- * REVERSE POLARITY OF GNL,GPL,GCL,GCM FOR LIMITING BECAUSE OF GA REVERSAL
- * ADD MULTIPLE POLES AND A ZERO BETWEEN GA STAGE AND GB STAGE
