Final answer:
In CMOS circuits, logical values are defined by high and low voltage levels, not by the passage or non-passage of current, making the statement false.
Step-by-step explanation:
In CMOS circuits, logical values of 1 and 0 are not defined by the passage or non-passage of current. Instead, these values are represented by high and low voltage levels. Logical '1' typically corresponds to a higher voltage, while logical '0' corresponds to a lower voltage (often ground). In CMOS technology, circuits use a combination of p-type and n-type metal-oxide-semiconductor field-effect transistors (MOSFETs) to create gates that can encapsulate these two states efficiently.
When a CMOS gate is in the 'off' state (representing a binary '0'), it draws no current or a very negligible leakage current. When it switches to the 'on' state (representing a binary '1'), the current is used transiently as the gate changes states. Hence, it is false that the logical values in CMOS circuits are defined by the passage or non-passage of current. CMOS technology is widely valued for its high noise immunity and low static power consumption relative to other logic families.
