sycan.components.basic.capacitor

Capacitor (SPICE C).

• DC: ideal open, i.e. not stamped.

• AC: admittance sC.

• Transient: admittance sC plus an initial-condition current injection C·v0 (from i_C(s) = sC·V(s) − C·v0).

Classes

Capacitor(name, n_plus, n_minus, value, *[, ...])

Linear capacitor; value is the capacitance.

class sycan.components.basic.capacitor.Capacitor(name, n_plus, n_minus, value, *, include_noise=None, ic=None)

Bases: Component

Linear capacitor; value is the capacitance.

ic is the optional initial voltage for transient analysis, with polarity v0 = V(n_plus) − V(n_minus) at t = 0⁻. Solver-time initial_conditions overrides win over this field.

Ideal capacitors are noiseless; include_noise is accepted for interface uniformity but only None / "all" (which expands to the empty set) are valid.

Parameters:

• name (str)

• n_plus (str)

• n_minus (str)

• value (Expr)

• include_noise (None | str | list[str] | tuple[str, ...] | frozenset[str])

• ic (Expr | None)
