An Accurate DAC Modeling Technique Based on Wavelet Theory
نویسندگان
چکیده
AbstmctTwo new DAC modeling techniques based on principles of wavelet theory are described in this paper. Macro model and mathematical model are developed for analog and digital circuit simulation, respectively for fast and accurate results using exponential function, damped sine wave, and linear waveform. An 8 bit DAC has been implemented to simulate and evaluate the models. The INLs of the macro and mathematical model based simulations are i O.ZLSB, which are the same a s HSPICE simulation. The DNLs of HSPICE simulation, macro model, and mathematical model based simulations are f 0.22LSB, + 0.28LSB, and f O.ZSLSB, respectively. The simulation times are 2.9 second for macro model, 0.15 second for mathematical model, and 68.09 second for HSPICE simulation.

Verification of an Evolutionary-based Wavelet Neural Network Model for Nonlinear Function Approximation
Nonlinear function approximation is one of the most important tasks in system analysis and identification. Several models have been presented to achieve an accurate approximation on nonlinear mathematics functions. However, the majority of the models are specific to certain problems and systems. In this paper, an evolutionary-based wavelet neural network model is proposed for structure definiti...

An accurate behavioral model of a DAC-embedded opamp (DAC-opamp) is developed for a yield-ensuring LCD column driver design. A lookup table for the V-I curve of the unit differential pair in the DAC-opamp is extracted from a circuit simulation and is later manipulated through a random error insertion. Virtual ground assumption simplifies the output voltage estimation algorithm. The developed be...
