This paper presents a three-channel frontend system for fetal monitoring applications which includes three amplification chains, an ADC and all power management circuitry needed to feed the different building blocks from a single 1.4V supply. The specifications of the proposed system (0.38μVrms equivalent input noise, 74.5dB dynamic range and 0.5 to 200Hz signal bandwidth) are determined according...
In this paper, an LTCC cavity backed array antenna in order to improve the radiation efficiency and bandwidth is proposed. LTCC cavity consists of several ground planes and dielectric layers with closely spaced metallic vias connected. It is shown that the size of an LTCC cavity has the effects on the performances of radiation and bandwidth for the antenna. This design is applied to Ferro A6 LTCC...
