A standing wave oscillator is described. The standing wave oscillator includes a transmission line, and an even number of gain stages. Each gain stage is connected to the transmission line, and each gain stage is located at a respective location along a length of the transmission line. The gain stages are configured to generate a standing wave oscillator signal along the length of the transmission line, when a supply voltage is applied to at least one end of the transmission line. The location of each gain stage is non-coincidental with an expected location of maximum amplitude of the standing wave oscillator signal.

Methods and systems for a distributed transmission line multiplexer for a multi-core multi-mode voltage-controlled oscillator (VCO) may comprise a plurality of voltage controlled oscillators (VCOs) arranged adjacent to each other, where each of the plurality of VCOs are operable to generate an output signal at a configurable frequency, an impedance matching circuit comprising a respective driver and impedance matching elements coupled to each of the plurality of VCOs, and an output device coupled to the impedance matching circuit. The impedance matching elements may include capacitors and inductors. Between each adjacent pair of the respective drivers coupled to each of the plurality of VCOs, the impedance matching elements may include two inductors coupled in series between the drivers and a capacitor coupled to ground and to a common node between the two inductors.

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.

Related systems, methods, and articles of manufacture are also disclosed.

Power and data are transmitted via a transformer including primary side and secondary side. A primary side signal is generated by coupling a first oscillator signal modulated with a data signal with a second oscillator signal that is selectively switched on and off. At the secondary side a secondary signal is generated. A demodulator demodulates the secondary signal to recover the data signal. A rectifier processes the secondary signal to recover a power supply signal controlled by switching on and off the second oscillator.
