A simplified block diagram of a continuous-time sigma-delta ADC comprises a sigma-delta modulator and a decimation filter (Fig. 1). Much like the discrete-time sigmadelta converters found in a ...

Abstract: This paper presents the design of a continuous time third order low pass sigma delta /spl Sigma//spl Delta/ modulator. The loop filter has been implemented by using an active RC-integrator ...

Continuous-time sigma-delta (CTΣΔ) analog-to-digital (A/D) conversion technology is challenging the conventional wisdom that pipeline A/D conversion is the only technique available for high dynamic ...

How a modulator works The working of a modulator can be explained using a conversion example. In Table 1 the headings X, B, C, D, and W correspond to points in the signal path of the block diagram in ...

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 ...

[1] CT stands for Continuous Time. That’s in contrast with discrete time (DT) circuits, namely sampled data circuits. Delta-sigma (DS) ADCs and modulators can either be CT or DT circuits. In CT DS, ...

Touting the industry’s best combination of operating frequency, dynamic range, and signal-to-noise ratio (SNR), the 16-bit AD9261 and AD9262 analog-to-digital converters (ADCs ...
