class kqcircuits.elements.capacitive_x_coupler.CapacitiveXCoupler[source]

Bases: Element

Capacitive coupler for testing FEM computations.


Child classes re-define this method to build the PCell.

classmethod get_sim_ports(simulation)[source]

List of RefpointToSimPort objects defining which refpoints should be turned to simulation ports for the given element class

Returns empty list if not implemented for Element subclass. When implementing this method, the best practice is for this method to have no “side effects”, that is all code contained within this method should only serve to derive the list of RefpointToSimPort objects and nothing else: no change in element’s geometry or parameter values.

  • cls – Element class, this is a class method

  • simulation – Simulation object where a cell of this element class is placed. Use this argument if you need to decide certain arguments for RefpointToSimPort objects based on simulation’s parameters


List of RefpointToSimPort objects, empty list by default

PCell parameters:

  • x_coupler_length (Double) - Length of Capacitive X Coupler, default=500

  • x_coupler_height (Double) - Height of Capacitive X Coupler, default=500

  • x_coupler_variant (String) - Coupler variant, either (+) or (x), default=+, choices=['+', 'x']

  • remove_capacitors (Boolean) - Remove capacitors from the X Coupler, default=False

  • finger_number (Int) - Number of fingers, default=2

  • finger_width (Double) - Width of a finger, default=10, unit=μm

  • finger_gap (Double) - Gap between the fingers, default=3, unit=μm

  • finger_gap_end (Double) - Gap between the finger and other pad, default=3, unit=μm
