摘要： Briefly, in accordance with one or more embodiments, in a pulse position and pulse position modulation out-phasing transmitter, the range of the phase angle, theta, may be divided into more than one range to drive a first power amplifier with a first range of theta, and to drive a second power amplifier with a second range of theta. In one or more embodiments, a main power amplifier is driven with a first phase range having a higher probability density function, and an overload power amplifier is driven with a first phase range having a lower probability density function. In one or more embodiments, a full adder may be used to combine the two phases wherein the sum signal is used to drive the main power amplifier, and the carry signal is used to drive the overload power amplifier.

摘要： An antenna module and communication device containing the antenna module are disclosed. The antenna module is disposed in a metal cavity. The antenna module includes a switched beam mm-wave antenna array having radiating elements separated by less than a wavelength of the radiating elements. The array is fed by a single transceiver chain. The array is disposed at the focal length of a low-profile mm-wave lens configured to steer the beam. A sub-10 GHz antenna is disposed closer to the opening of the cavity than the lens. The lens is a Fresnel Zone Plate lens having a focal length of less than about the wavelength of the beam, or a Saucer lens having shells of different refractive indexes and having a profile that is more than 6 times smaller than a Luneburg lens with a same focal length.

In an example, a wireless device can include a digital-to-time converter (DTC) configured to receive a phase data information from a baseband processor and to provide a first modulation signal for generating a wireless signal, a detector configure to receive the first modulation signal and provide an indication of nonlinearities of the DTC, and a pre-distortion module configured to provide pre-distortion information to the DTC using the indication of nonlinearities.

摘要： According to some embodiments, an all digital ramp generator may use a string of series connected delays or digital to time-based circuits to perform voltage ramp generation. Thus in some embodiments conventional operational amplifier circuits and relaxation oscillators may be replaced for generating triangular ramp waveforms for DC to DC or direct time-based DC to DC converters. The use of delay lines may produce sufficient resolution for many applications. Thus time domain techniques may afford a more digital approach that scales with process technology and allows high speed operation in some embodiments. A design based on use of inverters and capacitors may scale well with process technology. The decoder and drive logic may be integrated into the voltage ramp generation in some embodiments.

摘要： Embodiments provide a voltage controlled oscillator (VCO) having reduced single-ended capacitance. In one embodiment, the VCO may include a transformer, a capacitor bank, and a gain stage. The transformer may include a primary inductor and a secondary inductor, and the secondary inductor may be inductively coupled to the primary inductor. The capacitor bank may be coupled to the secondary inductor and may provide a majority of a total capacitance of the VCO. The gain stage may be coupled to the primary inductor and configured to receive a supply signal and to drive a differential current in the primary inductor, thereby inducing an output signal across the secondary inductor having a frequency equal to a resonant frequency of the VCO.

摘要： A wireless transceiver may include a power amplifier that uses an envelope tracker. The envelope tracker may include stacked buck switching supply modulators, each having two different supply voltages. In one embodiment, the two different supply voltages are higher and lower supply voltages, which relaxes the voltage head room on the switching regulator and allows the use of thin gate fast transistors in some embodiments.

摘要： Film bulk acoustic resonators (FBARS) have resonant frequencies that vary with manufacturing variations, but tend to be matched when in proximity on an integrated circuit die. FBAR resonant frequency is determined using a fractional-N synthesizer and comparing phase/frequency of an output signal from the fractional-N synthesizer to a reference. The reference may be derived from a low frequency crystal oscillator, an external signal source, or a communications signal.
