The development of low noise amplifiers (LNAs) in complementary metal–oxide–semiconductor (CMOS) technology has been at the forefront of modern wireless communication research. CMOS LNAs are integral ...

How do you sort through this overwhelming number of devices? One way is to start by selecting the optimal process technology. Most manufacturers clearly label an op amp as CMOS, bipolar, or even ...

This diagram shows the standard layout of transistors in cell phone power amplifiers, at left, and a new highly efficient amplifier design, at right. The new design could help make possible ...

Transimpedance amplifiers (TIAs) implemented in CMOS technology remain critical components in a wide range of applications, from optical communication systems to sensing and instrumentation. These ...

In this exclusive series, Chipworks, one of the world's leading IC reverse-engineering houses, provides detailed functional and circuit analysis of significant new integrated circuits. Coupling actual ...

Nujira has been demonstrating how its envelope-tracking (ET) technology could make it practical to use CMOS power amplifiers (PAs) in the RF circuits of 4G smartphones. According to Jeremy Hendy, v-p ...

Linear Technology’s new family of CMOS amplifiers delivers DC precision at low supply current. The company says that the LTC6078 dual and LTC6079 quad op amps offer a breakthrough combination of ...

Members can download the PDF ebook. When I present seminars, I often ask the members of the audience to hold up their hands if they think bipolar op amps have better gain and linearity than CMOS. I ...
