A Digital Sweep (Chirp) Generator With Extremely Small Memory Size And High Level Of The Spurious Free Dynamic Range
نویسندگان
چکیده
This paper presents an efficient technique to extremely increase the performance of Pedersen’s digital chirp generator concerning the level of the Spurious-Free Dynamic Range (SFDR) and size of the memory. The proposed digital chirp generator uses the piecewise parabolic interpolation to decrease the memory size and system complexity while maintaining excellent spectral performance in comparison with the other techniques.

Improving adaptive resolution of analog to digital converters using least squares mean method
This paper presents an adaptive digital resolution improvement method for extrapolating and recursive analog-to-digital converters (ADCs). The presented adaptively enhanced ADC (AE-ADC) digitally estimates the digital equivalent of the input signal by utilizing an adaptive digital filter (ADF). The least mean squares (LMS) algorithm also determines the coefficients of the ADF block. In this sch...
متن کاملA dynamic element matching technique for reduced-distortion multibit quantization in delta-sigma ADCs
A multibit analog-to-digital converter can achieve high resolution with a lower order modulator and lower oversampling ratio than a single-bit design. However, in a multibit modulator, quantization level errors in the internal multibit quantizer can limit the modulator’s signal-to-noise-and-distortion and spurious-free dynamic range. For a CMOS analog-to-digital converter using a flash analog-t...
متن کاملDistance Dependent Localization Approach in Oil Reservoir History Matching: A Comparative Study
To perform any economic management of a petroleum reservoir in real time, a predictable and/or updateable model of reservoir along with uncertainty estimation ability is required. One relatively recent method is a sequential Monte Carlo implementation of the Kalman filter: the Ensemble Kalman Filter (EnKF). The EnKF not only estimate uncertain parameters but also provide a recursive estimat...
