Functions

merge_all_bboxes(lb)

class bag3_analog.layout.highpass.HighPassDiffCore(temp_db: bag.layout.template.TemplateDB, params: bag.util.immutable.Param, **kwargs: Any)

Bases: xbase.layout.res.base.ResArrayBase

A differential RC high-pass filter.

classmethod get_schematic_class() → Optional[bag.design.module.Module]

classmethod get_params_info() → Dict[str, str]

Returns a dictionary from parameter names to descriptions.

Returns:

param_info – dictionary from parameter names to descriptions.

Return type:

Mapping[str, str]

classmethod get_default_param_values() → Dict[str, Any]

Returns a dictionary containing default parameter values.

Override this method to define default parameter values. As good practice, you should avoid defining default values for technology-dependent parameters (such as channel length, transistor width, etc.), but only define default values for technology-independent parameters (such as number of tracks).

Returns:

default_params – dictionary of default parameter values.

Return type:

Mapping[str, Any]

draw_layout()

Draw the layout of this template.

Override this method to create the layout.

WARNING: you should never call this method yourself.

connect_resistors(bias_idx) → Tuple[bag.layout.routing.base.WireArray, bag.layout.routing.base.WireArray, bag.layout.routing.base.WireArray, bag.layout.routing.base.WireArray, bag.layout.routing.base.WireArray, int, int]

Connect the resistors in series. bias_idx sets which track to draw the vm bias wire on

draw_mom_cap(nser, xl, xr, cap_spx, cap_spy, cap_margin) → Tuple[bag.layout.routing.base.WireArray, bag.layout.routing.base.WireArray, bag.layout.routing.base.WireArray, bag.layout.routing.base.WireArray, bag.layout.routing.base.WireArray, bag.layout.routing.base.WireArray]

class bag3_analog.layout.highpass.HighPassArrayCore(temp_db: bag.layout.template.TemplateDB, params: bag.util.immutable.Param, **kwargs: Any)

Bases: xbase.layout.res.base.ResArrayBase

An row array of RC high-pass filter.

classmethod get_schematic_class() → Optional[bag.design.module.Module]

classmethod get_params_info() → Dict[str, str]

Return type:

Mapping[str, str]
