What is RF CMOS technology?

RF CMOS is a metal–oxide–semiconductor (MOS) integrated circuit (IC) technology that integrates radio-frequency (RF), analog and digital electronics on a mixed-signal CMOS (complementary MOS) RF circuit chip.

What is SiGe BiCMOS technology?

BiCMOS: the best of two worlds By integrating the RF, analog and digital parts on a single chip, ST’s BiCMOS SiGe (Silicon-Germanium) technology drastically reduces the number of external components while optimizing power consumption.

What is SiGe process?

SiGe processes essentially build on established semiconductor process approaches such as Si CMOS, by depositing a thin layer of Ge on top of the Si substrate.

Which process is used for CMOS?

The CMOS can be fabricated using different processes such as: N-well process for CMOS fabrication. P-well process. Twin tub-CMOS-fabrication process.

What is the difference between CMOS and BiCMOS?

BiCMOS combines both Bipolar and CMOS technologies in single IC. As we know CMOS has merits over bipolar in areas of low power dissipation, large noise margins and greater packing densities. Bipolar has merits over CMOS in areas of faster switching speed and large current cababilities.

What are the advantages of BiCMOS process compare with the CMOS?

It follows that BiCMOS technology offers the advantages of: 1) improved speed over CMOS, 2) lower power dissipation than Bipolar (simplifying packaging and board requirements), 3) flexible I/Os (TTL, CMOS, or ECL), 4) high performance analog, and 5) latchup immunity [1.2].

What is the meaning of Sige?

go on, go ahead, proceed, continue part. go on, proceed, continue. O sige.

Is Sige a compound semiconductor?

Silicon is made from a single element, and therefore is not a compound semiconductor. Most compound semiconductors are from combinations of elements from GroupIII and GroupV of the Periodic Table of the Elements (GaAs, GaP, InP and others).

What is CMOS and its function?

CMOS stands for “Complementary Metal Oxide Semiconductor.” The CMOS battery powers the BIOS firmware in your laptop [2]. BIOS needs to remain operational even when your computer isn’t plugged into a power source. When your computer gets unplugged, BIOS relies on the CMOS battery for power.

What is CMOS technology hence explain the differences between NMOS and CMOS technology?

CMOS stands for Complementary Metal-Oxide-Semiconductor whereas NMOS is a negative channel metal oxide semiconductor. CMOS and NMOS are two logic families, where CMOS uses both MOS transistors and PMOS for design and NMOS use only field-effect transistors for design.

What is IBM SiGe BiCMOS and RF CMOS?

This paper provides a detailed description of the IBM SiGe BiCMOS and rf CMOS technologies. The technologies provide high-performance SiGe heterojunction bipolar transistors (HBTs) combined with advanced CMOS technology and a variety of passive devices critical for realizing an integrated mixed-signal system-on-a-chip (SoC).

Why BiCMOS SiGe/Si devices?

Ge/Si devices provide a possible solution for these kinds of high-speed applications, as BiCMOS SiGe technology has already been proved in CMOS foundries [15]. In addition, low field transport is much faster in Ge than in Si, and high field transport is similar between both materials.

What is the main challenge of Ge/Si optical devices at CMOS foundries?

The main challenge of Ge/Si optical devices at CMOS foundries is to realize high quality process of a pure Ge layer grown on Si. Silicon photonics is one of the promising technologies for high speed optical fiber communications [1].

Why CMOS and BiCMOS monolithic integration?

The CMOS and BiCMOS monolithic integration compatibility of this work is also attractive for Ge CMOS and near-infrared sensing and communication integration. IC transistor technologies determine important circuit properties such as operation frequency, gain, noise, large signal performance, DC power consumption, circuit complexity and costs.
