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 ...

Delta-sigma modulation has emerged as a pivotal technique in CMOS technology for high-resolution analogue‐to‐digital conversion. By utilising oversampling and noise-shaping strategies, this method ...

Abstract: The opamp in the integrators of a continuous-time delta-sigma modulator (CTDSM) has stringent noise and linearity requirements, which lead to large power dissipation. In this paper, a ...

My last column showed how a single-stage delta-sigma modulator (DSM) produces an output that is a sum of the low pass-filtered input signal and the high pass-filtered quantization noise (see “Part 4,” ...

Incremental analog-to-digital converters (ADCs) and delta-sigma modulators represent two advanced architectures that have been pivotal in high-precision signal processing. Incremental ADCs convert ...

In part one, I compared the different Analog to Digital Converters (ADC) and the roles and properties of Delta Sigma ADC’s. I covered a lot of the theory behind these devices, so in this installment, ...

Based on the amount of e-mail I received after Part 3 of this series (Nov. 7, 2008, p. 18; www.electronicdesign.com, ED Online 19948), many of you have already guessed that an incremental integrator ...
