Delta-sigma ADCs in a nutshell

By Bonnie Baker

• Delta-sigma ADCs in a nutshell - 12/14/2007 - EDN
  : Part one of a three-part series exploring the basic topology and functions of delta-sigma ADCs.
  
• Delta-sigma ADCs in a nutshell, part 2: the modulator - 1/17/2008 - EDN
  : Unlike most quantizers, the delta-sigma modulator includes an integrator that shapes the quantization noise.
  
• Delta-sigma ADCs in a nutshell, part 3: the digital/decimator filter - 2/21/2008 - EDN
  : A digital-filter function attenuates the noise, and the decimator function slows the output data rate.
  
• Delta-sigma ADCs in a nutshell, part 4: noise versus data rate - 3/20/2008 - EDN
  : "Effective resolution" describes the useful bits from an analog-to-digital conversion as they relate to signal noise.
