Abstract
The present disclosure relates to a reconfigurable multicore inductor capacitor (LC) oscillator comprising a plurality of oscillator cores. The oscillator may be configured at run-time, at manufacturing, or at production, which may allow for the tailoring of operating characteristics of the oscillator, such as phase noise, electromagnetic interference, or power consumption, for a specific application after production. The cores are coupled through an interconnect network to a common electrical signal output. A subset of the cores may be selectively enabled while the remainder of the cores is disabled. The ability to enable only a subset of the cores allows the total number of enabled cores to be reconfigurable. Furthermore, the direction in which oscillation current flows through the inductor of the cores may be configured. Reconfiguring the number of enabled cores and/or the oscillation current direction in the cores allow operating characteristics of the oscillator to be tailored after production.
