BIDIRECTIONAL-INJECTION COUPLED OSCILLATOR

摘要

An oscillator (102) includes bidirectional-injection technology to permit phase cancellation of coupled signals for phase injection of energy into the oscillator substantially in phase with the oscillator's internal energy. In an example embodiment, the oscillator includes at least two energy phase injectors or couplers configured to generate and inject energy at balanced phases with respect to the phase of the energy of the tank's energy- injecting component. The couplers of the oscillator may be coupled with multiple oscillators in a multiphase configuration for generation of multiphase signals. The signals may be utilized as multiphase clock signals, such as quadrature clock signals. Such oscillators may, for example, be implemented as clock generators for timing of synchronous data systems or for modulation, detection and/or image rejection in radio- frequency and high speed communications.
