zero.analysis.ac.signal module

class zero.analysis.ac.signal.AcSignalAnalysis(*args, **kwargs)[source]

Bases: zero.analysis.ac.base.BaseAcAnalysis

AC signal analysis

calculate(input_type, **kwargs)[source]

Calculate responses.

Parameters

input_type (str) – Input type, either “voltage” or “current”.

Other Parameters

  • frequencies (np.ndarray or sequence) – The frequency vector to calculate the response with.

  • node, node_p, node_n (Node) – The node or nodes to make the input. The node parameter sets a single, grounded input, whereas node_p and node_n together create a floating input.

  • print_equations (bool, optional) – Print the circuit equations.

  • print_matrix (bool, optional) – Print the circuit matrix.

Returns

Solution – Solution containing noise spectra at the specified sink (or projected sink).

property has_current_input

property has_voltage_input

Check if circuit has a voltage input.

property input_component_index

Input component’s matrix index

property input_node_index

Input node’s matrix index

property right_hand_side_index

Right hand side excitation component index
