Integrated voltage controlled oscillator-based transmitter
View Patent ↗Methods and systems for an integrated voltage controlled oscillator (VCO)-based transmitter and on-chip power distribution network are disclosed and may include supplying bias voltages and/or ground to a chip utilizing conductive lines. One or more VCOs and low-noise amplifiers (LNAs) may each be coupled to a leaky wave antenna (LWA) integrated in the bias voltage and/or ground lines. One or more clock signals may be generated utilizing the VCOs, which may be transmitted from the LWAs coupled to the VCOs, to the LWAs coupled to the LNAs. RF signals may be transmitted via the LWAs, and may include 60 GHz signals. The LWAs may include microstrip and/or coplanar waveguides, where a cavity length of the LWAs may be dependent on a spacing between conductive lines in the waveguides. The LWAs may be dynamically configured to transmit the clock signals at a desired angle from a surface of the chip.
