Bringing ultrawideband to handsets
UWB uniquely offers a handset the potential to wirelessly connect peripheral devices that were previously reserved for wired connections.
Timing-driven Simulink FPGA synthesis
The latest Simulink blocksets take in top-level system timing constraints to achieve a level of performance previously achievable only with hand coded HDL. Here's how it works.
Frequency domain tutorial, part 1: Dealing with ambiguity
Here's what you need to know about the mathematics and notation of FFTs and the discrete frequency domain. We start by discussing the ambiguities of discrete signals.
Tip of the Week: High power 3.3-volt bus for a Li-ion handheld device
Popular 3.3-volt bus systems derived from a single cell lithium-ion battery often suffer from low efficiency, the usual polarity inversion, and the need for complex circuitry. Here's how you can apply a suitable synchronous buck-boost controller to secure positive results.
Demystifying UHF Gen 2 RFID, HF RFID
Whether you are considering using high frequency (HF) RFID technologies or ultra high frequency (UHF) Gen 2, the first question you must ask yourself is why? This article provides information to help you make informed choices on tags and technology.
Accurate prediction of harmonic levels from non-linear gain expansions, Part 1
Wish you had a better understanding of how to predict third harmonic distortion levels? Kendall Castor-Perry suggests that more careful attention to the derivation and manipulation of the underlying power series can produce a result that converges on the exact value.
Characterizing Nanometer CMOS PLLs, Sigma-Delta ADCs and AGCs
The verification of analog/RF blocks presents challenges when using a digital fastSPICE simulator. The use of an analog fastSPICE simulator mitigates them.
60GHz: Achieving the ultimate wireless dream
Using sophisticated design and fabrication techniques, research labs are getting closer to realizing 60GHz chips in silicon. When that happens, consumer price points can be met and wireless design becomes a whole new ballgame. But first, engineers must overcome five major challenges.
