Why is CMOS logic mostly preferred?

Cmos is complementary MOSFETs which includes both PMOS and NMOS. CMOS is more preferred because it provides pure logic 1 and pure logic 0 . If you consider NMOS as driver and load as active or passive elements .

What is the difference between mosfet and CMOS?

Basically mosfet acts like an electronic switch, as well as voltage regulator. CMOS means complementary metal oxide semiconductor feild effect transistor. CMOS is the combination of both PMOS AND NMOS. Basically CMOS acts as a inverter.

Why is VLSI industry completely using CMOS?

The reasons for the dominant use of CMOS Technology in the fabrication of VLSI chips are reliability, low power consumption, considerably low cost and most importantly scalability.

What is the difference between VLSI and CMOS?

In recent days most of the vlsi designs are based on TTL logic i.e using BJT s. The main disadvantage was higher power consumption. In CMOS Technology the power consumption and speed low than TTL. But power consumption is more preferred than speed. So CMOS is preferred for vlsi designs.

What is the difference between TTL and CMOS microcontroller?

In CMOS Technology the power consumption and speed low than TTL. But power consumption is more preferred than speed. So CMOS is preferred for vlsi designs. Generally lower power consumption because CMOS draws the most current when it switches state.

What is the CMOS technology?

CMOS technology uses both MOS transistors. CMOS processing steps can be broadly divided into two parts. Transistors are formed in the Front-End-of-Line (FEOL) phase, while wires are built in the Back-End-of-Line (BEOL) phase. Index terms: IC, SSI, TTL, MSL, VLSI, CMOS, MOS, ULSI and MOSFET. 1.

Why is CMOS more preferred over NMOS for power supply?

CMOS is more preferred because it provides pure logic 1 and pure logic 0 . If you consider NMOS as driver and load as active or passive elements . You will get pure logic 1 with passive element (resistor as load ) but pure logic 0 is not achievable as there is Vt voltage drop . Similar case with active load.
