Abstract
Disclosed is an injection locked oscillator array circuit device and method for designing injection locking circuit in sub-millimeter wave band. An injection locked oscillator array circuit device comprises: an oscillator array comprising a plurality of oscillators arranged in a square matrix; an injection locking circuit configured to inject an injection locking signal into some of the oscillators in the oscillator array.
Claims3
An injection locked oscillator array circuit device, comprising:
- an oscillator array comprising a plurality of oscillators arranged in an N×N square matrix, wherein N is an integer greater than or equal to 4;
- an injection locking circuit configured to inject an injection locking signal into a proper subset of the plurality of oscillators, less than all of the plurality of oscillators, the proper subset being located in a symmetric structure within the oscillator array, wherein the injection locking circuit comprises:
- a first power divider configured to distribute the injection locking signal and output distributed signals through a first transmission line and a second transmission line;
- a second power divider configured to distribute a signal delivered through the first transmission line and inject distributed signals into a first oscillator and a second oscillator among the oscillators via a third transmission line and a fourth transmission line;
- and
- a third power divider configured to distribute a signal delivered through the second transmission line and inject distributed signals into a third oscillator and a fourth oscillator among the oscillators via a fifth transmission line and a sixth transmission line,
- wherein the first oscillator, the second oscillator, the third oscillator and the fourth oscillator are oscillators located in a same row or a same column of the N×N square matrix.
