Asad Ali Abidi developed RF CMOS technology at UCLA during the late 1980s to early 1990s.. Pakistani engineer Asad Ali Abidi, while working at Bell Labs and then UCLA during the 1980s–1990s, pioneered radio research in metal–oxide–semiconductor (MOS) technology and made seminal contributions to radio architecture based on complementary MOS (CMOS) switched-capacitor (SC) technology.

A radio-frequency power amplifier (RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency (RF) signal into a higher-power signal. [1] Typically, RF power amplifiers are used in the final stage of a radio transmitter , their output driving the antenna .
This interest is bolstered by the pervasiveness of wireless capabilities in electronics. Current research focuses on integrating the RF power amplifier (PA) with CMOS technology, either by using MOSFETs or SiGe HBTs, on RF CMOS mixed-signal integrated circuit chips.
The same year, the company released its first product, the model 101 op amp, [10] which was a hockey-puck sized module used in test and measurement equipment. [11] In 1967, the company published the first issue of its technical magazine, Analog Dialogue. [12]
The silicon-based RF LDMOS (radio-frequency LDMOS) is the most widely used RF power amplifier in mobile networks, [2] [3] [4] enabling the majority of the world's cellular voice and data traffic. [5] LDMOS devices are widely used in RF power amplifiers for base-stations as the requirement is for high output power with a corresponding drain to ...
This is more serious in modern CMOS technologies, which transistors have smaller output resistance due to shorter channel length. To achieve high gain as well as high output swing, multi-stage amplifiers have been invented. To implement two-stage amplifier, one can use FC amplifier as the first stage and a common source amplifier as the second ...
A RF distribution amplifier is a high−performance distribution amplifier for analog RF signals. It takes one RF signal and carries it to multiple identical outputs. [1]
These processes also include steps for the deposition of precision resistors, and high Q RF inductors and capacitors on-chip, which are not needed in a "pure" CMOS logic design. BiCMOS is aimed at mixed-signal ICs, such as ADCs and complete software radio systems on a chip that need amplifiers, analog power management circuits, and logic gates ...
