Low-Pressure Small MEMS Accelerometer Using Sigma-Delta Modulation
Encapsulation of MEMS accelerometers in vacuum is advantageous, since it allows integration with other sensors, leading to size and cost reduction. One technique to operate MEMS accelerometers in vacuum is the use of closed-loop Sigma-Delta modulation ...

Analysis of Booth Multiplier based Conventional and Short Word Length FIR Filter
The optimized implantation of digital filters has remained one of the challenging tasks, for FPGA (Field- Programmable Gate Array) based system designers, due to the involvement of very complex circuitry for multiplication.

A Hierarchical Modulation Enabled SNR Allocable Delta-Sigma Digital Mobile Fronthaul System
Internet of everything is being build up rapidly, which causes much higher requirements towards the flexibility of communication resources, especially the adaptivity of the fronthaul to various transmission distances and capacities.

Design Sign of Delta Sigma Wattmeter [PDF]
Instantaneous power in a load is measured by multiplying the voltage across it by the current flowing through it. The multiplication is achieved in a delta sigma wattmeter by using two samplers rather than a multiplier.

SNDR sensitivity analysis for cascaded ΣΔ modulators [PDF]
Cascade, single and multi-bit, ΣΔ architectures provide stable, high order quantization noise shaping used in high resolution A/D conversion. One major disadvantage of cascaded ΣΔ topologies is the extreme SNDR sensitivity to gain mismatch between the ...
