Untersuchung integrierbarer Empfängerkonzepte mit niedriger Zwischenfrequenz für frequenzmodulierte Systeme
… applications with a special attention on low power consumption and an economical implementation rather than a high clock frequency. In particular medical and sensor applications need power and area efficient radio systems. Here the production volumes are lower in comparison to portable …

A contribution to continuous-time quadrature bandpass sigma-delta modulators for low-IF receivers
… (CT-QBP SDMs). CT-QBP SDMs is well suited for low-IF receivers due to some significant advantages over other implementations. Firstly, the possible design methodologies have been defined and compared. The proposed inverse method is desirable for the design of CT-QBP SDM. Starting from CT loop …

RF hardware design of a stepped frequency continuous wave ground penetrating radar
… by the University of Stellenbosch for the specific use of ground penetrating radar. Measurements with the first generation system proved the concept of SFCW GPR and thus a dedicated second generation system was planned. A SFCW GPR system was designed to replace the first generation system. …

Low-Power RF Front-End Design for Wireless Body Area Networks
… a meager amount of power consumption poses significant design challenges. In order to address these issues, IEEE has recently developed a draft of IEEE 802.15.6 standard dedicated to low bit-rate short-range wireless communications on, in, or around the human body. Commercially available SoC …

The Analysis and Design of Phase-tunable Low-Power Low-Phase-Noise I/Q Signal Sources for Analog Phase Calibrated Transceivers
Due to the demand for low-cost, small-form factor and large-scale integration of system-on-chip wireless transceivers, the image-reject, zero-IF and low-IF receiver architectures have become the main topologies used in mainstream wireless communication systems. Consequently, signal sources with …
