Physical Width in Integrated Circuits (IC) Formulas

Physical Width refers to the width of the channel region between the source and drain terminals. This channel width determines the current-carrying capability of the MOSFET. And is denoted by W_p. Physical Width is usually measured using the Meter for Length. Note that the value of Physical Width is always positive.

FAQ

What is the Physical Width?

Physical Width refers to the width of the channel region between the source and drain terminals. This channel width determines the current-carrying capability of the MOSFET. Physical Width is usually measured using the Meter for Length. Note that the value of Physical Width is always positive.

Can the Physical Width be negative?

No, the Physical Width, measured in Length cannot be negative.

What unit is used to measure Physical Width?

Physical Width is usually measured using the Meter[m] for Length. Millimeter[m], Kilometer[m], Decimeter[m] are the few other units in which Physical Width can be measured.
