Gate Leak Currents

This section describes the parameters and equations for gate leak currents.

Instance Parameters

Parameter	Description
`Aforward`	Forward gate leakage current coefficient. Default value is `0.0`.
`Areverse`	Reverse gate leakage current coefficient. Default value is `0.0`.

If Aforward and Areverse are both 0.0, gate leak current is also 0.0.

Model Parameters

Parameter	Description
`Bforward`	Forward gate leakage current coefficient in `pow()`. Default value is `0.0`.
`Breverse`	Reverse gate leakage current coefficient in `pow()`. Default value is `0.0`.
`Cforward`	Forward gate leakage current coefficient in `exp()`. Default value is `0.0`.
`Creverse`	Reverse gate leakage current coefficient in `exp()`. Default value is `0.0`.
`Tcc`	Gate leakage current temperature coefficient. Default value is `0.0`.
