A 0.8V, 88dB Dual-Channel Audio ∆Σ DAC with Headphone Driver

چکیده
Battery-powered portable audio devices require low-voltage, low-power, and medium-accuracy digital-to-analog converters (DACs). The proposed structure is inherently suitable for lowvoltage and low-power applications. Fig. 1 shows the block diagram of the complete DAC system. The input of the DAC is a 16-bit serial digital signal DIN; the analog output AOUT drives the headphone load (16Ω parallel with 300pF).

A 100-dB gain-corrected delta-sigma audio DAC with headphone driver
An oversampled digital-to-analog converter (DAC) with a 100-dB A-weighted dynamic range is presented. It uses a switched-capacitor (SC) array to transfer the sampled charges directly into the headphone driver. The overall DAC gain is precisely controlled by a novel reference stage. A new dynamic element matching algorithm, based on split-set data-weighted averaging (SDWA), is used to improve th...

Wireless and wireline communication applications demand A/D converters with MHz signal bandwidth and 14b or better resolution. Compared with switched-capacitor (SC) implementations, continuous-time (CT) Σ∆ modulators have the advantages of lower power consumption and intrinsic anti-alias filtering. Moreover, as the sampler is inside of the CT Σ∆ loop (see the upper half of Fig. 3.5.1), any samp...
متن کاملBinaural Cue Coding: Rendering of Sources Mixed into Amono Signal
This paper reviews Binaural Cue Coding (BCC). BCC is a lossy technique for either reducing either a number of source signals or a multichannel audio signal to one audio channel plus side information. In the case when a number of source signals (e.g. separately recorded instruments) are reduced to one audio channel plus side information, the BCC synthesis allows rendering of each source as if th...
متن کاملAn 11 GS/s 1.1 GHz Bandwidth Interleaved ΔΣ DAC for 60 GHz Radio in 65 nm CMOS
This work presents an 11 GS/s 1.1 GHz bandwidth interleaved ∆Σ DAC in 65 nm CMOS for the 60-GHz radio baseband. The high sample rate is achieved by using a two-channel interleaved MASH 1-1 architecture with a 4-bit output resulting in a predominantly digital DAC with only fifteen analog current cells. Two-channel interleaving allows the use of a single clock for the logic and the multiplexing w...
