Design of a 2-Bit Sigma-Delta Modulator for Scintillation Waveform Capture

Abstract: Sigma-delta modulation is a common technique used in analog-to-digital conversion. It has been shown that it can be implemented in a field-programmable gate array (FPGA) using minimal ...

Photonic Arbitrary Waveform Generation Based on Delta-Sigma Modulation and Spectrum Stitching

Abstract: This Letter introduces a novel approach to photonic arbitrary waveform generation (PAWG) that employs delta-sigma modulation (DSM) and spectrum stitching techniques. The approach divides a ...

Sigma-delta modulation improves resolution in programmable interrupt controller analog outputs

One popular way to reconstruct analog signals in microcontrollers (µCs) is through pulse width modulation (PWM). However, this modulation produces a large number of harmonic components, which limits ...

The basics of sigma delta analog-to-digital converters

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 Figure 2. For this ...
