Principles of Sigma Delta Modulation for Analog to Digital Converters

moto高级工程师所做的delta-sigma调制的书籍，由浅入深，图文并茂，讲解非常清楚，适合初学者。 Sigma-Delta conversion technology is based on oversampling, noise shaping, and decimation filtering. There are many inherent advantages in S-D based analog-to-digital converters. The major advantage being that it is based predominantly on digital
