Analysis of Decimation on Finite Frames with Sigma-Delta Quantization
In Analog-to-digital (A/D) conversion on oversampled bandlimited functions, integration of samples in blocks before down-sampling, known as decimation, has been proven to greatly improve the efficiency of data storage while maintaining high accuracy. In particular, when coupled with the Σ∆ quantization scheme, the reconstruction error decays exponentially with respect to the bit-rate. Here, a s...
متن کاملTime-Mode Signal Quantization for Use in Sigma-Delta Modulators
The rapid scaling in modern CMOS technology has motivated the researchers to design new analog-to-digital converter (ADC) architectures that can properly work in lower supply voltage. An exchanging the data quantization procedure from the amplitude to the time domain, can be a promising alternative well adapt with the technology scaling. This paper is going to review the recent development in t...
متن کاملDesign of a Decimation Filter for Novel Sigma-delta Modulator
The steps involved in the design of decimation filter for high-resolution sigma-delta (ΣΔ) A/D converter are described. The design of a decimation filter is proposed that employs three stage – one Cascaded Integrator Comb filter (CIC) followed by two finite impulse response (FIR) filters. This approach eliminates the need for multiplication, requires a maximum clock frequency equal to the sampl...

متن کاملDesign Simulation of Decimation Filter for Sigma Delta Converters
The purpose of this paper is to present several filter topologies used for decimation of sigma delta modulated digital signals in order to choose the optimised filter architecture with regards to an efficient implementation. The filter is suited for data conversion and measurement applications. A second order 1-bit sigma delta modulator will be considered as the front-end A/D converter. The sub...
