摘要： Digital correction of multibit ADAC nonlinearities for error feedback DACs is provided. The integral nonlinearity (INL) error of the multibit ADAC is estimated (on line or off line) by a low-resolution calibration ADC (CADC) and stored in a random-access memory (RAM) table. The INL values are then used to compensate for the ADAC's distortion in the digital domain. When this compensation is combined with mismatch-shaping techniques such as DWA, the resolution requirement for CADC can be relaxed significantly. The implementation of the proposed correction circuit for error-feedback modulators is inherently simple, since the correction only needs a digital summation without any additional digital filtering.

摘要： The invention provides a single digital communication link between system-side and line-side circuitry in a DAA, capable both of carrying data signals and of transferring a substantial amount of power to the line-side circuitry. The invention comprises a system-side interface circuit, a line-side interface circuit, and an isolation barrier including a transformer. Each interface circuit is capable of connection to an upstream communication circuit (either line-side or system-side), from which it may receive data signals to be transmitted across the isolation barrier to the other interface circuit, and to which it may pass data signals received across the isolation barrier from the other interface circuit. The line-side interface circuit may further include a rectifier and a storage device.

摘要： Frequency dependent I/Q imbalance in real I/Q filter pairs compensation may be performed using a simple compensation module, placed in the receiver/transmitter chain, with a gain adjustment coefficient and a delay adjustment coefficient. The gain adjustment coefficient may be determined by amplitude measurements conducted at a selected frequency near the center of the band-pass region of the filters. The delay adjustment coefficient may be determined by phase measurements conducted at a selected frequency near the edge of the band-pass region of the filters. Statistical analysis may be used to determine types of real filters that are better suited for the compensation method and to select the test frequencies that should be used.

摘要： The invention provides a signal-powered integrated circuit (IC). The IC comprises an integrated circuit die including a ground node, a supply node, and a first terminal for receiving a digital data signal having data content and a predetermined energy. A receive buffer formed on the integrated circuit die is connected to the first terminal and capable of receiving the data content associated with the digital data signal. A rectifier is also formed on the integrated circuit die. The rectifier includes a first diode connected between the first terminal and the ground node and a second diode connected between the first terminal and the supply node. The rectifier is configured to rectify the digital data signal and pass at least a portion of the digital data signal's predetermined energy to the supply node. Each of the first and second diodes is capable of withstanding an ESD impulse.
