A low power dual-band variable gain low noise amplifier (DB-VGLNA) with multiple tunable gain control terminals was designed and implemented. In the proposed DB-VGLNA, a serial-parallel resonant filter network was used to achieve dual-band input impedance matching. In order to enhance gain tunability, three gain-adjustment stages, i.e. cascode amplifier with active inductor as variable load, common-gate...
The unscented Kalman filter (UKF) is an extension of the Kalman filter for nonlinear systems where a set of weighted sigma points are used to simulate the distribution of the state random variable. The performance of the filter depends heavily on the selection of sigma points, and the computational cost is proportional to the number of sigma points used. It was previously shown that n + 2 (but not...
Due to the differ sensors distributing position, operation performance and some uncertainty factors effect in the industrial process, the measured parameter's excursion inevitably is caused in the real world. To obtain the accurate measuring value, a spatial-temporal fusion algorithm based support degree and self-adaptive weighted theory is put forward in this paper. Considering the temporal and special...
