The Design of Sigma-Delta Analog to Digital Converters for Digital Audio
نویسندگان
چکیده
This paper presents the design of a second-order Sigma-Delta modulator for digital audio. This modulator has been designed at 3 V power supply with oversampling ratio of 256 and simulated in a 0.6 μm CMOS technology. The simulated results give SNDR of 96 dB for a 24 KHz signal bandwidth. The sampling frequency is 12.288 MHz and the Nyquist rate of the modulator is 48 KHz.

Time-Mode Signal Quantization for Use in Sigma-Delta Modulators
The rapid scaling in modern CMOS technology has motivated the researchers to design new analog-to-digital converter (ADC) architectures that can properly work in lower supply voltage. An exchanging the data quantization procedure from the amplitude to the time domain, can be a promising alternative well adapt with the technology scaling. This paper is going to review the recent development in t...
متن کاملAn Overview of Sigma-Delta Converters - IEEE Signal Processing Magazine
A lthough real world signals are analog, it is often desirable to convert them into the digital domain .using an analog to digital converter (ADC). Motivating designers to apply this conversion is the efficient transmission and storage of digital signals. Digital representation of an audio signal, for example, allows CD players to achieve virtually error free storage using optical disks [l]. In...
متن کاملHdl-a Modelling of Switched-current Delta Sigma A/d Converters
Abstract: Switched Current (SI) is a very interesting analog technique to perform interface circuits in mixed analog/digital systems because it is compatible with a low cost digital CMOS process (single poly technologies). The attempt of this work is to shed some light on the SI delta-sigma converter design method making use of an analog Hardware Description Language. To demonstrate the perform...
متن کاملSampling Jitter in Audio A/D Converters
This paper provides an overview of the effects of timing jitter in audio sampling analog-to-digital converters (ADCs), i.e. PCM (conventional or Nyquist sampling) ADCs and sigma-delta (Σ∆) ADCs. Jitter in a digital audio is often defined as shortterm fluctuations of the sampling instants of a digital signal from their ideal positions in time. The influence of the jitter increases particularly w...
متن کاملImproving adaptive resolution of analog to digital converters using least squares mean method
This paper presents an adaptive digital resolution improvement method for extrapolating and recursive analog-to-digital converters (ADCs). The presented adaptively enhanced ADC (AE-ADC) digitally estimates the digital equivalent of the input signal by utilizing an adaptive digital filter (ADF). The least mean squares (LMS) algorithm also determines the coefficients of the ADF block. In this sch...
