Different types of RF passive-integrated wide-band bandpass filters (BPFs) and bandstop filters (BSFs) in CMOS technology that operate at the millimeter-wave region are presented. Firstly, the use of integrated 3-D inductors that exploit their parasitic capacitance to functionalize as LC tanks is shown. They enable highly-miniaturized on-chip wide-band BPF design as a result of the 3-D structure, along with transmission-zero (TZ) creation in the BPF response. Afterwards, a class of on-chip BSFs based on broadside-coupled meandered-line resonating cells is reported. Simulated and measured results of various built proof-of-concept RF-CMOS chips of the addressed BPF and BSF concepts are provided. These families of passive-integrated RF filtering components may find application in future wireless-communication radio systems as 5G.
