sycan.components.blocks.integrator

Continuous-time integrator block.

Implements H(s) = k / (s + leak) — ideal pure integrator when leak = 0, lossy / leaky integrator otherwise. The latter is useful when an exact pure integrator would make the DC operating point indeterminate (the ideal integrator has an infinite DC gain, so this block leaves its output floating in DC mode).

The auxiliary stamping is identical to a frequency-dependent VCVS controlled by the differential input.
