An inductor has a conductor layer formed by multiple concentric co-planar turns of a first metal layer (e.g., ultra-thick metal (UTM)) adapted to receive current at a frequency of at least one gigahertz. The multiple turns of the first metal layer proceed from an innermost turn to an outermost turn, and a stacking layer of a second metal is provided over each of the first metal layer turns except at least the innermost turn, thereby optimizing the Q of the inductor.

Stacked metal inductor

An inductor has a conductor layer formed by multiple concentric co-planar turns of ultra-thick metal (UTM) adapted to receive current at a frequency of at least one gigahertz. The multiple turns of UTM proceed from an innermost turn to an outermost turn, and aluminum stacking is provided over all of the UTM turns except at least the innermost turn, thereby optimizing the Q of the inductor.

An integrated circuit (IC) comprises a plurality of metal layers; a seal ring arranged around a perimeter of the IC and included in at least a portion of the plurality of metal layers; a first coil included in the IC; and a bypass conductor included in at least one metal layer of the plurality of metal layers and having at least a first end and a second end electrically coupled to the seal ring to form a bypass ring around the first coil.

A tunable wideband distribution circuit for transmitting a wireless signal over a transmission line is disclosed. The tunable wideband distribution circuit may include a programmable gain buffer, wherein the gain of the programmable gain buffer is based at least in part on a frequency of the wireless signal. The tunable wideband distribution circuit may also include a tuning element configured to modify an effective impedance of the transmission line based at least on the frequency of the wireless signal, wherein the tuning element is electrically coupled to the transmission line.
