The requirement of effective analog to digital conversion and accuracy gives growth to converters. The sigma delta modulator have a salient feature of shaping the noise, such that noise reduces from ...

Shown is a simplified continuous-time sigma-delta ADC model, comprising a sigma-delta modulator and a decimation filter. The DT-S? input structure typically implements switched capacitors, and CT-S?

Sigma-delta converters are in wide use among applications that demand high precision and accuracy. A variant of the sigma-delta architecture, called the continuous-time sigma delta (CT-S?), has found ...

In my previous article on EDN, The fully Digital radio transmitter: Is it real of more hype?, there was a great deal of commentary about other alternatives with a digital approach to radio. I these ...
