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 ...

Abstract: An exact discrete-time analysis of the moments and spectra of the quantization noise of a discrete-time single-loop sigma-delta modulator with a DC input is presented. An exact difference ...

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 ...

Recently I stumbled across a research paper describing how an Analog-to-Digital (ADC) converter can be implemented almost entirely within an FPGA. The paper illustrated how a differential input LVDS ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...

Abstract: A method for improving the signal-to-noise ratio (SNR) of sigma-delta modulators with one-bit quantization is presented. The two-level feedback signal of a standard sigma-delta modulator is ...

The CS5374 is a dual, high-performance amplifier and delta-sigma modulator with high input impedance amplifier and differential analog input. It has low total harmonic distortion as well as low power ...

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 ...

AD7403 isolated sigma-delta modulator achieves industry’s highest accuracy current and voltage measurement. NORWOOD, Mass.--(BUSINESS WIRE)--Analog Devices, Inc. (NASDAQ: ADI) introduced today the ...
