In Industrial motor or servo control applications, accurate current measurement is a critical as part of the control loop. Not only has the current measurement need to be as accurate as possible, it ...
With 16-bit resolution and SNR of 86 dB, STMicro’s ISOSD61 isolated modulator enhances performance and reliability in industrial motor control. The second-order sigma-delta modulator offers a choice ...
A previous column, Oversampling Reduces Quantization Errors, included a diagram for, and a short description of, a single-stage sigma-delta analog-to-digital converter (ADC). The ADC produced a stream ...
Delta-sigma modulation is a cornerstone approach for high-resolution analogue-to-digital conversion, combining oversampling with active noise shaping to achieve superior signal fidelity. In these ...
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 ...
