Spirea AB is a Swedish fabless semiconductor company developing highly integrated low-power, low-cost radio solutions for the Wireless LAN and PAN markets. This article describes how we assembled a ...

With a new breed of analog/mixed-signal foundries arriving on the scene, fabless and fab-lite companies can create a huge variety of high-yielding designs. As a result, these fabless and fab-lite ...

CMOS mixers are integral components in modern radio frequency (RF) circuit design, enabling frequency conversion in wireless systems while prioritising low power consumption. Recent progress in ...

This article will help you move advanced mixed-signal & wireless designs away from the design-build-test (-hope) paradigm, towards getting it right by design, the first time, with confidence. Articles ...

Active inductors have emerged as a transformative component in CMOS radio frequency (RF) circuit design, effectively replacing traditional passive inductors with active semiconductor networks. By ...

A novel method for deriving a set of transistor design specs based upon performances of a library of Figure-of-Merit (FOM) circuits. System-on-Chip designs require low cost integration of analog and ...

Figuring out how to integrate more and more analog and digital blocks on a single chip has become a difficult task. A primary challenge is that these mixed-signal blocks have diverse design styles.

Mixed-signal devices are at the heart of many advanced systems today because of the need to interact with the outside world, but designing and verifying these systems is getting harder. There are ...

In the first of a multi-part series on how to design a custom chip for under $1,000, our Analog Editor gets you started with a Magnificent 7 list of textbooks. TinyTapeout offers a course that ...
