The use of Delta-Sigma modulation in fully digital transmitter architectures has emerged as a versatile means of achieving high spectral purity and wideband agility without reliance on analogue mixers ...

In my previous column, I took a historical approach to delta-sigma modulation with the single-slope converter (May 8, p. 18, ED Online 18747). Jim Williams of Linear Tech responded, and he sent me a ...

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 ...

The delta-sigma ADC tackles the application demands of a slow analog signal that requires a high signal-to-noise-ratio (SNR) and wide dynamic range. But, the delta-sigma converter is not the only ...

Bob Adams is an Analog Devices fellow. He is known for his contributions to the invention of log-domain filters, the design of the first monolithic asynchronous sample-rate converters for digital ...

Delta-sigma (ΔΣ) converters may sound complex, but at their core, they are all about precision. In this post, we will peel back the layers and uncover the fundamentals behind their elegant design. At ...

September 21, 2005-- Only a month after announcing the first set of Sigma-Delta Data Converters, Intrinsix announces the availability of three more sets to round out the family. The first set, ...

Class-D audio amplifiers, also known as switching amplifiers, achieve high power efficiency by operating their output transistors as rapid on/off switches. An input audio waveform is converted into a ...
