摘要： Circuitry for establishing a traveling wave on a rotary traveling wave oscillator is described. The circuitry includes a gain portion that establishes a wave in a preferred direction by degenerating any wave traveling opposite to the preferred direction and regenerating any wave traveling in the preferred direction. If there are two such gain portions, each having opposite preferred directions, then a wave that is presently established in one direction can be degenerated and a new wave can be established in the opposite direction, thereby achieving reversibility of the traveling wave in real time. Each of the gain portions included in a plurality of regeneration/degeneration elements present on the rotary oscillator. Each of the regeneration/degeneration elements is connected to a pair of taps on the oscillator, the taps being separated by a direction dependent phase difference.

摘要： A phase interpolation circuit based on injected passive capacitances and an inductance for forming a resonator. The circuit conducts at least a first reference signal having a first phase component and a second reference signal having a second phase component shifted from the first phase component. By selectively switching the first reference signal and/or the second reference signal through one or more capacitances, an interpolated third signal having a third phase component between the first phase component and the second phase component can be generated. An inductor is connected with one or more of the capacitances for forming a resonant circuit to boost the signal level of the interpolated third signal. By utilizing resonance, an improved signal-to-noise ratio may be obtained for the interpolated third signal. An additional amplification stage, secondary to the resonant circuit, may be incorporated for further amplifying the signal level of the interpolated third signal.

摘要： In one embodiment, the present invention includes a transmitter having a baseband, a multiplexer, a digital-to-analog converter unit, and/or a Chireix combiner. The baseband transmits components of an in-phase signal and a quadrature-phase signal to the multiplexer. The multiplexer generates a first signal and/or a second signal which have a phase difference which matches only a single predetermined phase difference. The single predetermined phase difference should be selected to ensure that the Chireix combiner is optimized for efficiency. Thus, a phase of the first signal or the second signal can have a phase of the in-phase signal or the quadrature-phase signal to ensure that the phase difference between the second signal and the first signal matches only the single predetermined phase difference. The Chireix combiner receives the first analog signal and the second analog signal.

摘要： A low cost high-efficiency all-digital transmitter using all-digital power amplifiers (“DPA”) and various mapping techniques to generate an output signal, which substantially reproduces a baseband signal at a carrier frequency. A baseband signal generator generates a baseband signal which is quantized by a signal processor using a quantization map. A DPA control mapper outputs control signals to phase selectors using the quantized signal and a quantization table. Each phase selector receives one of the control signals and outputs a waveform at a carrier frequency with a phase corresponding to the control signals, or an inactive signal. Each DPA in a DPA array has an assigned weight, receives one of the waveforms from the phase selectors, and outputs a power signal according to the weight of the DPA and the phase of the received waveform. The combined power signal substantially reproduces the baseband signal at the carrier frequency.
