CMOS logic gates use complementary arrangements of enhancement-mode N-channel and P-channel field effect transistor. Since the initial devices used oxide-isolated metal gates, they were called CMOS (complementary metal–oxide–semiconductor logic). In contrast to TTL, CMOS uses almost no power in the static state (that is, when inputs are not changing). A CMOS gate draws no current other than leakage when in a steady 1 or 0 state. When the gate switches states, current … WebThis set of Digital Electronics/Circuits Multiple Choice Questions & Answers (MCQs) focuses on “Digital Circuits Questions and Answers – Transistor Transistor Logic(TTL or T2L)”. 1. …
