class xbase.layout.mos.tech.MOSTech(tech_info: bag.layout.tech.TechInfo, lch: int, arr_options: Mapping[str, Any])[source]

Bases: abc.ABC

An abstract class for drawing transistor related layout.

This class defines various methods use to draw layouts used by MOSBase.

Parameters:

  • tech_info (TechInfo) – the TechInfo object.

  • lch (int) – the channel length.

  • arr_options (Mapping[str, Any]) – process-specific options for the transistor array.

abstract property blk_h_pitch: int[source]
