Symmetrical -   People usually can't be bothered with the dotted lines.  Almost always know where the bulk is connected - just clutters the schematic. Not clear if n or p-type  "Digital" device schematic:  Analogue: Slightly misleading as assymetrical (but okay because we normally have the source at the same end) - looks like BJT. Easier to understand circuits.  Might add a bulk terminal - when you need a special case for the node not connected normally.  ## Special Transistors Low threshold or depletion device - common to draw it like this:  Thick channel - special device (can be used for any symbol) Or higher voltage on drain/source:  Non-standard, but read in the context of the design. ## Summary  [^1] --- # References [^1]: [vr-4602-wk03-sc02-symbols](../../Spaces/University/ELEC4602%20–%20Microelectronics%20Design%20and%20Technology/Lectures/W2/vr-4602-wk03-sc02-symbols.mp4)
