Find out how a digital technique performs multiplication on two bitstreams and avoids the cost of the analog multiplier.

Unlike most quantizers, the delta-sigma modulator includes an integrator that shapes the quantization noise. The noise spectrum at the modulator output is not flat. More important, in a frequency ...

A single-loop third-order modulator topology suitable for low power and high integration multi-standard receiver is described. 1 The trade-offs in the modulator design are also presented and explained ...

Pulse density modulation is just the analog portion of a delta-sigma analog-to-digital converter (ADC). It coverts an analog signal into a digital density stream.

Part 3 looks at the design complexity of alias-rejection solutions and highlights the alias-free nature of continuous-time sigma-delta (CTSD) ADCs, which improves the immunity ...

Release Summary Highest accuracy isolated sigma-delta modulator for precision current and voltage measurement in DC/AC power conversion applications such as motor drives, solar and wind inverters.

A quadrature modulator from Linear Technology is optimised for direct conversion from baseband to the 850-965MHz frequency band for GSM, EDGE, CDMA2000 basestations and 900MHz RFID readers.

How to optimise digital modulation accuracy in an IQ modulator? Bruce Hemp and Peter Stroet from Linear Technology describe how a vector signal analyser ...

This articles addresses the issues of how to design effective delta-sigma modulators for wireless receivers that need to support GSM, DECT, and wideband CDMA (W-CDMA) operation. A single-loop ...
