Level 49 parameter sets in WRspice may include BSIM3v3.2
parameters, though historically HSPICE level 49 was based on
BSIM3v3.1. The following parameters are new for v3.2:
- ALPHA1, ACDE, MOIN, NOFF, VOFFCV
All except ALPHA1 are used in a new capacitance model ( CAPMOD=3). ALPHA1 modifies the substrate current equation as
follows:
Isub ~ (ALPHA0 + ALPHA1*Leff) / Leff
