This paper presents a novel low power high linear sub-harmonic mixer for direct-down conversion receiver, in which an inductive connection between RF and LO stages is used to improve the linearity and enhance the gain of mixer. A comparison is done between two circuits for two possible conditions, high gain medium linearity (HGML) and high linearity medium gain (HLMG), and recently published works...
In this paper, SystemC-AMS modeling capabilities of RF non-linear behaviors are studied. Thus, based on a satellite receiver case-study, SystemC-AMS simulation results are compared to several classical system-level simulation approaches and to measurements. It appears that SystemC-AMS allows a good compromise between modeling accuracy and simulation execution-time speed. Moreover, the modeled RF front-end...
In this paper, we propose the method that reduces the power consumption by decreasing the network traffic on the ZED having the power saving feature. By using the proposed method, in order to recognize the ON-point time period of the ZEDpsilas RF receiver, the parent node does not receive a data request periodically from the ZED. Therefore, the network traffic between the ZED and the parent node is...
