model_name
|
(Optional) Name of model. Must begin with a letter but can contain any character except whitespace and period '.' |
|
value
|
Capacitance (Farads) |
|
initial_condition
|
Initial voltage if UIC specified on .TRAN statement.
|
|
local_temp
|
Capacitor temperature (???MATH???°???MATH???C) |
|
tc1
|
First order temperature coefficient |
|
tc2
|
Second order temperature coefficient |
|
vc1
|
First order voltage coefficient |
|
vc2
|
Second order voltage coefficient |
|
BRANCH
|
May be 0 or 1. 0 is the default. This parameter determines the internal formulation of the capacitor and affects how the IC parameter is implemented. When BRANCH=0, the capacitor looks like an open circuit during the DC operating point and the IC parameter has no effect unless UIC is specified for a transient analysis. If BRANCH=1, the capacitor looks like a voltage source during dc operating point with a magnitude equal to the value of the IC parameter. BRANCH=1 makes it possible to specify circuit startup conditions. See Alternative Initial Condition Implementations for an example.

|
mult
|
Device multiplier. Equivalent to putting mult devices in parallel.
|
|
dtemp
|
Differential temperature. Similar to local_temp but is specified relative to circuit temperature. If both TEMP and DTEMP are specified, TEMP takes precedence.
|
|
esr
|
Effective series resistance. If non-zero (the default value), a resistor of value esr will be connected in series with the capacitor. The resulting implementation of a series RC network is more efficient and offers better convergence than using a separate R and C. This is especially the case if the capacitor has a high value and is non-grounded.
Important: this resistor is noiseless; if the noise in the ESR is important in your design, you should use a separate resistor and omit this parameter in the capacitor.
