Abstract
Wireless microdevices are getting smaller and smaller, and in this special issue seven papers address a few miniaturization challenges in the biomedical field, which are common across different applications. Kargaran et al. [1] proposes a new ultra-low-voltage ultra-low-power LNA, where the reduced current consumption of only 160 μA, on a supply as low as 0.18 V, has potential to enable future RF receivers for ultra-low-power implantable devices [...].
