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

A delta-sigma converter uses many samples from the modulator to produce a stream of 1-bit codes. The delta-sigma ADC accomplishes this task by using an input-signal quantizer running at a high sample ...

This file type includes high resolution graphics and schematics. Delta-sigma analog-to-digital converters (ADCs) are fascinating—almost mythical in their ability to support low- to medium-speed and ...

All engineers have spreadsheets on their computer and know how to use them. The input is just a column of data, and the output is plotted. Pulse density modulation is just the analog portion of a ...

The transition from second-generation (2G) to third-generation (3G) wireless cellular systems requires multi-standard adaptability in a wireless receiver. An important answer to this request is the ...

The web is filled with introductions to Delta Sigma modulation (also sometimes referred to as Sigma Delta modulation) in the context of Delta Sigma converters. Unfortunately, the ones I’ve looked at ...

The PWM sigma-delta modulator is a special type of 1-bit sigma-delta modulator that produces a pulse width modulated (PWM) output signal with a fixed repetition frequency. A fixed repetition ... The ...
