Low voltage sigma-delta modulators

Proceedings of the IEEE 2nd Dallas CAS Workshop on Low Power/Low Voltage Mixed-Signal Circuits & Systems (DCAS-01) (Cat No 01EX454) DCAS-01, 2001
Sigma delta modulators are nice solutions to achieve high resolution with relatively simple analog circuits,Sigma delta are based on the oversampling technique, If the sampling frequency is higher than the Nyquist limit only a fraction of the quantization noise power falls in the signal band,A digital filter which rejects the out-of-band noise is ...

Synchronization of Sigma Delta Modulators

2012
The paper deals with the synchronization of two chaotic Sigma-Delta Modulators. The synchronization is reached via two modulators: one of the modulators is used to code the input information into a bitstream, while the second demodulator is used to decode the obtained bitstream into the original state of the applied input signal.

High-Order Sigma-Delta Modulators

2018
This chapter comprises two sets of exercises. In the first set, the main properties of a third-order modulator (MOD3) are investigated, following the procedure of previous chapters. Based on the simulations proposed, it is demonstrated that modulators with noise-shaping order higher than two can be unstable for some or even all possible inputs, usually

Sigma-delta modulation neural networks

2014
Sigma-delta modulation can be used to model the waveforrn coding process of biological neurons. The discrete-time model can greatly simplify the analysis that are nontrivial with traditional continuous time models formulated with differential equations.
