The single analog filter (SAF) hybrid filter bank (HFB) ADC is presented in this paper. Base on SAF architecture, a calibration model is derived to integrate the analog filter's realization errors and channel mismatches errors. A two-channel SAF HFB ADC with 12-bit resolution and 200MHz sampling rate is implemented. The experimental results show that the average spurious-free dynamic range (SFDR)...
This paper presents a flexible frequency-dependent equivalent model (FDEM), which can be used to calibrate the nonlinear errors of HFB. Then, a two-channel 12 bits 200Msps HFB ADC prototype is implemented. The validity and feasibility of the proposed method is verified by making use of analyzing the output data of the actual HFB system. The experimental results show that the average spurious-free...
The quality of certificate/report is the most important thing for the measurement technology institutions as the final products in the process of metrological verification, calibration and test. This paper presents a dynamic management system for measurement certificate/report based on SOA. In accordance with the analysis of the measurement certificate/report elements, three aspects of the effectiveness...
