摘要： Tunable injection locked (IL) dividers having enhanced locking range, good phase noise performance, and low power consumption are disclosed. In an exemplary design, an apparatus (e.g., a wireless device) includes an oscillator and at least one IL divider. The oscillator provides an oscillator signal at a first frequency. The at least one IL divider receives the oscillator signal and provides an output signal at a second frequency, which is related to the first frequency by an overall divider ratio for the IL divider(s). Each IL divider may be calibrated based on a target frequency of that IL divider. Each IL divider may be calibrated (e.g., by tuning at least one adjustable capacitor) to obtain an oscillation frequency within a predetermined tolerance of the target frequency of that IL divider. The oscillator may be calibrated based on a target oscillation frequency of the oscillator.

摘要： Techniques for providing transformer-based CMOS oscillators capable of operation with low voltage power supplies. In an exemplary embodiment, an LC tank is provided at the drains of a transistor pair, and the inductance of the LC tank is mutually magnetically coupled to an inductance between the gates of the transistor pair. A separate complementary transistor pair is also coupled to the LC tank. A further exemplary embodiment provides an LC tank at the gates of a transistor pair, as well as for three-way coupling amongst a tank inductance, an inductance between the gates of the transistor pair, and an inductance between the gates of a complementary transistor pair.

摘要： A frequency divider circuit is described. The frequency divider circuit includes a first cross-coupling. The first cross-coupling includes a first cross-coupled transistor with a first gate. The first gate is separately biased. The first cross-coupling also includes a second cross-coupled transistor with a second gate. The second gate is separately biased. The first gate is coupled to the second cross-coupled transistor and the second gate is coupled to the first cross-coupled transistor.
