Abstract: Device that can be implanted into the brain, in particular that of a small animal (16), for the detection of radiation emitted by disintegration of a radioisotope, characterized in that it comprises an implantable detector (10) made of a semiconductor material and comprising a number of individual detectors (22), the device also including a system (14) of amplification, shaping, counting and wireless remote transmission circuits that are connected to the individual detectors (22) and are intended to be worn by the animal (16), the latter being awake and free to move.

Abstract: An eletronic package comprising a printed circuit board on which are mounted a plurality of decoupling capacitors is disclosed. A carrier component electrically connects an integrated circuit to the printed circuit board through a plurality of solder balls. The plurality of solder balls comprises at least one solder ball for the integrated circuit ground voltage connection and at least one solder ball for the integrated circuit power voltage connection. The plurality of decoupling capacitors is organized as a set of ‘n’ capacitors ranged from a lower capacitor value Clow to a higher capacitor value Chigh such that the range Clow to Chigh of the ‘n’ capacitor values is a function of the frequency range Flow to Fhigh on which the integrated circuit operates.
