摘要： Apparatus and methods perform gain, clipping, and phase compensation in the presence of I/Q mismatch in quadrature RF receivers. Gain and phase mismatch are exacerbated by differences in clipping between I & Q signals in low resolution ADCs. Signals in the stronger channel arm are clipped differentially more than weaker signals in the other channel arm. Embodiments herein perform clipping operations during iterations of gain mismatch calculations in order to balance clipping between the I and Q channel arms (105 and 108, respectively). Gain compensation coefficients (120 and 122) are iteratively converged, clipping levels are established, and data flowing through the network (100) is gain and clipping compensated. A compensation phase angle and phase compensation coefficients (154 and 166) are then determined from gain and clipping compensated sample data. The resulting phase compensation coefficients are applied to the gain and clipping corrected receiver data (144 and 148) to yield a gain, clipping, and phase compensated data stream (on 170 and 172).

摘要： A passive continuous time linear equalizer (CTLE) (102) includes an alternating current (AC) coupling capacitor (116) coupled in series between an input node (114) and an output node (118) of the passive CTLE. An electrostatic discharge protection device (120) is coupled in parallel to the input node. An inductor (128) coupled in parallel to a node (124) between the input node and the output node. Further, the passive CTLE includes a variable resistor (126) coupled in series between the inductor and a ground (122). Increased impedance of the inductor at higher frequencies portions of the input signal operate to boost a gain of the equalizer at the higher frequencies without active power by over-terminating the input signal.

摘要： Aspects include an apparatus and a method for performing Second Order Input Intercept Point (IIP2) calibration of a Digital-to-Analog (DAC) during a full-duplex mode receive operation. In some aspects, a plurality of correlation values are obtained, indicating an amount of IMD energy of an RF signal, wherein the correlation values are associated with IIP2DAC values of a DAC. In some aspects, the apparatus can calculate a mixer bias value, based on the correlation values, and adjust a bias value of a mixer according to the determined bias value. The apparatus can obtain the correlation values, calculate the bias value, and adjust the bias value of the mixer during the full-duplex mode receive operation. In some aspects, the apparatus can thus improve IIP2 of the mixer and reduce IMD energy in a receive signal, during the receive operation, without the need of standby or factory calibration.

摘要： A high-speed digital distribution system is presented that includes a transmission line bus that carriers modulated digital signals and reference signals. The transmission line bus has a first end electrically connected to a bus interface that modulates digital data onto said transmission line bus and demodulates modulated digital data signals that it receives from the transmission line bus. The bus interface can transmit and receive a reference signal. At least one digital component interface is in electromagnetic communication with the transmission line bus, and each digital component interface can also modulate digital data onto the transmission line bus and can demodulate modulated digital data signals received from the transmission line bus, and can transmit and receive a reference signal. The transmission line bus communicates modulated digital data in association with the reference signal between and among an external device connected to the bus interface and the at least one digital component interface. In one embodiment, the digital data is quadrature amplitude modulated with an encoding that uses one to five bits for the phase component and zero to three bits for the amplitude component. In another embodiment the transmission line bus has characteristic impedance and has matched terminations at its first and second ends.

摘要： Methods for driving a lossy transmission media with an energy wave defined by a an exponential waveform function. The propagation delay and attenuation of the wave is a function of an exponential coefficient, and its propagation velocity is essentially constant and independent of displacement. Utilizing relationships between the propagation velocity, exponential coefficient, attenuation, and transmission line parameters, one may effectively model various transmission media. One may also determine unknown transmission line parameters, waveform exponential coefficients, attenuation, and/or propagation velocities by utilizing those relationships. By modulating the exponential coefficient, information may be encoded onto a waveform.
