Abstract: A power saving improvement in an injection locked oscillator (ILO) used is described. The ILO circuitry comprises a feedback path to provide a finecal (M-bit fine calibration signal). The feedback path need not be active at all times; only when an event occurs that requires the feedback path to update the value of the finecal signal. A monitor is provided to sense the occurrence of such event which may be, for examples, an end of a time period or a predetermined change in temperature. When the event occurs, the feedback path is activated to update the value of the finecal signal.

The comparator circuit is configured to compare a voltage at a sense node in the replica circuit and a reference voltage and to provide to the current-mode logic differential amplifier and, via a feedback loop, to the replica circuit, an output that drives the sense node toward the reference voltage.

Abstract: A method includes determining a phase error for a first clock signal and a second clock signal and determining an offset based on the phase error for the first clock signal and the second clock signal. The method also includes adding the offset to a phase of the first clock signal to produce a first adjusted clock signal and subtracting the offset from a phase of the second clock signal to produce a second adjusted clock signal. A phase error for the first adjusted clock signal and the second adjusted clock signal is smaller than the phase error for the first clock signal and the second clock signal.

Abstract: A broadband panel array antenna includes a polarization layer, a radiating layer and a feed layer which are sequentially stacked from top to bottom. The feed layer is used for converting a single path of TE10 mode signals into a plurality of paths of same-power in-phase TE10 mode signals and transmitting the plurality of paths of TE10 mode signals to the radiating layer. The radiating layer is used for radiating the plurality of paths of TE10 mode signals from the feed layer to a free space.

The broadband panel array antenna has the advantages of being low in side lobe, high in gain and efficiency, and low in machining cost.
