    Abstract: Certain aspects of the present disclosure are generally directed to a structure for a balanced-unbalanced (balun) transformer. For example, certain aspects of the present disclosure provide a transformer that generally includes a first winding having a first terminal coupled to an input node and a second terminal coupled to a reference potential node. The transformer may also include a first impedance coupled between a center tap of the first winding and the reference potential node, and a second winding magnetically coupled to the first winding and having a first terminal coupled to a first differential node of a differential output pair, a second terminal coupled to a second differential node of the differential output pair, and a center tap coupled to the reference potential node.

    Abstract: A capacitor radio frequency (RF) shielding structure may include a ground plane partially surrounding a coupling capacitor in an RF signal path. The ground plane may include a first ground plane portion extending between a positive terminal of the RF signal path and a negative terminal of the RF signal path. The ground plane may include a second ground plane portion extending between the positive terminal and the negative terminal of the RF signal path. The second ground plane portion may be opposed the first ground plane portion. The capacitor RF shielding structure may also include a patterned shielding layer electrically contacting the first ground plane portion and/or the second ground plane portion. The patterned shielding layer may electrically disconnecting a return current path over the patterned shielding layer to confine a return current to flowing over the first ground plane portion or the second ground plane portion.

    Abstract: Various aspects described herein relate to low-loss multi-band multiplexing schemes for a wireless communications system, for example, a 5th Generation (5G) New Radio (NR) system. In an aspect, a multiplexer for multi-band wireless communications comprises at least one tuning component configured to transmit or receive at least one signal within a frequency band that is selected from a plurality of frequency bands. The multiplexer further comprises at least one combining component, communicatively coupled with the at least one tuning component, configured to transmit or receive the at least one signal within the selected frequency band. In an aspect, the at least one tuning component is integrated on a chip and the at least one combining component is not integrated on the chip.

    Abstract: An integrated circuit includes a capacitor (e.g., a folded metal-oxide-metal (MOM) capacitor) formed in the lower BEOL interconnect levels, without degrading an inductor's Q-factor. The integrated circuit includes the capacitor in one or more back-end-of-line (BEOL) interconnect levels. The capacitor includes multiple folded capacitor fingers having multiple sides and a pair of manifolds on a same side of the folded capacitor fingers. Each of the pair of manifolds is coupled to one or more of the folded capacitor fingers. The integrated circuit also includes an inductive trace having one or more turns in one or more different BEOL interconnect levels. The inductive trace overlaps one or more portions of the capacitor.
