Design of Interpolative Sigma Delta Modulators via a Semi-infinite Programming Approach
This paper considers the design of interpolative sigma delta modulators (SDMs). The design problem is formulated as two different optimization problems. The first optimization problem is to determine the denominator coefficients. The objective of the optimization problem is to minimize the energy of the error function in the passband of the loop filter in which the error function reflects the n...
متن کاملOutput Filter Aware Optimization of the Noise Shaping Properties of Delta-Sigma Modulators via Semi-Definite Programming
The Noise Transfer Function (NTF) of ΔΣ modulators is typically designed after the features of the input signal. We suggest that in many applications, and notably those involving D/D and D/A conversion or actuation, the NTF should instead be shaped after the properties of the output/reconstruction filter. To this aim, we propose a framework for optimal design based on the Kalman–Yakubovich–Popo...
متن کاملGlobal stability, Limit cycles and Chaotic Behaviors of Second Order interpolative Sigma Delta modulators
It is well known that second order lowpass interpolative sigma delta modulators (SDMs) may suffer from instability and limit cycle problems when the magnitudes of the input signals are at large and at intermediate levels, respectively. In order to solve these problems, we propose to replace the second order lowpass interpolative SDMs to a specific class of second order bandpass interpolative SD...
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 کاملOptimal design of discrete-time delta sigma modulators
Optimal Design of Discrete-Time ∆Σ Modulators by Matthew Edward Jackson Dr. Peter A. Stubberud, Examination Committee Chair Professor of Electrical Engineering University of Nevada, Las Vegas In this thesis, optimal signal transfer functions (STFs) and noise transfer functions (NTFs) for discrete time delta sigma (∆Σ) modulators are determined. For a given oversampling rate (OSR), these STFs an...
