RF receivers placed directly on coil in conjunction with fibre-optical data transmission can provide various advantages for the design of array coils in terms of avoidance of dangerous sheath currents, common-mode noise and unwanted coil to coil interactions, as well as reduction of cable weight and routing problems. This helps to further increase channel counts but also usability or even wear-ability of RF receive arrays. Here we present first results from coil designs employing fully integrated (in 130 nm CMOS technology) digital receivers with a form factor and power requirements to be placed directly on the coil footpoint.
