摘要： Embodiments include circuit devices and methods for re-clocking an input signal. In an embodiment, a circuit device includes a data storage element having a data input to receive a digital data stream having a first clock rate and including a clock input to receive a clock signal having a second clock rate. The data storage element further includes logic to adjust edge timing of transitions within the digital data stream based on the clock signal to produce a modulated output signal having a power spectrum with spectral nulls at a desired frequency and its harmonics without changing an average data rate.

摘要： A calibration circuitry includes an adjustable capacitor, a voltage generator, a reference voltage generator, and a controller. The reference voltage generator provides a reference voltage. The voltage generator provides a measurement voltage that depends on the capacitance of the adjustable capacitor. The capacitance of the adjustable capacitor varies in response to a control signal. The controller provides the control signal based on the relative values of the reference voltage and the measurement voltage.

摘要： A bias system is disclosed including a calibration bus to which a controller, a reference bias source, a master bias source, and first and second slave bias sources are coupled. The controller varies a control code sent over the calibration bus to the master bias source until a particular control code is found that causes the bias signal of the master bias source to equal a desired bias value which is provided by the reference bias source. The controller then sends the particular control code to the first and second slave bias sources to cause the first and second slave bias sources to generate a bias signal having the same desired bias value as the master bias source. Isolation between load circuits coupled to the first and second bias sources is thus enhanced while providing low noise, stable operation.

摘要： Systems and methods are disclosed for the co-location of radio frequency (RF) antennas in portable devices, portable devices and their docking stations and related systems, and devices with restrictive space constraints to allow for simultaneous receive (RX) and transmit (TX) operation without degradation. The systems and methods disclosed overcome RX channel degradation, receiver performance, and other problems seen in prior solutions. More particularly, transmit and receive antennas are oriented to provide for cross-polarization of their electro-magnetic fields, are oriented to allow one or both antenna to fall within null regions of the other antenna, and/or oriented with both cross-polarization and null region considerations in mind. Other variations and implementations are also described.
