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 ...

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?

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, ...

The 18-bit delta-sigma MCP3421 analog-to-digital converter (ADC) is the highest-resolution ADC available in an SOT-23 package, according to Microchip Technology Inc. The low-power device features an ...

One of the most challenging tasks in Analog to Digital Converter (ADC) design is to adapt the cicuitry to ever new CMOS process technology. For digital circuits the number of gates per square mm app.

Delta-sigma converters with sinc (sinx/x) digital filters change the signal chain’s complex antialiasing-filter requirements to a simple, first-order, passive filter. With this “easy-to-design” ...

This article will explain continuous-time sigma-delta (CTSD) ADC technology in a less traditional approach, enabling signal chain designers toenvision a new class of easy to use precision ADC ...

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 ...

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 ...

n Part 3 of our CTSD precision ADCs article series, we will highlight the alias free nature of CTSD ADCs, which improves the immunity to interferers without any added peripheral design. Part 1 ...
