Capacitor Model

Type Name: c

The capacitor model contains process information that may be used to compute the capacitance from strictly geometric information.

Capacitor Model Parameters
name parameter units default example
cj junction bottom capacitance F/M2 - 5e-5
cjsw junction sidewall capacitance F/M - 2e-11
defw default device width M 1e-6 2e-6
narrow narrowing due to side etching M 0.0 1e-7
The capacitor has a capacitance computed as
C = cj . (l-narrow)(w-narrow) + 2cjsw . (l+w-2 . narrow)
