*
* Features:
* gm adjustable over 6 decades.
* Excellent gm linearity.
* Linearizing diodes.
* Wide supply range of +/-2V to +/-22V.
*
* Note: This model is single-pole in nature and over-estimates
* AC bandwidth and phase margin (stability) by over 2X.
* Although refinement may be possible in the future, please
* use benchtesting to finalize AC circuit design.
*
* Note: Model is for single device only and simulated
* supply current is 1/2 of total device current.
