Correction: Mariappan, S.G. et al. Polymer Magnetic Composite Core Based Microcoils and Microtransformers for Very High Frequency Power Applications. Micromachines, 2016, 7, 60

In the published paper [1], there are two errors in

Table 5. Survey on the state of the art microtransformers (pure RF microinductors are excluded). All the devices except the ones which marked with (*) were characterized using 50 Ω load.

, both of which correspond to the reported results of a paper authored by Macrelli et al. in 2014 [48]. The correct value of the inductance per DC resistance of this paper is 73256 nH$/\mathsf{\Omega }$, and the correct value of the core volume is 4.32 mm${}^3$. Therefore, Table 5 should read as follows:
