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.
摘要翻译：提供了用于误差反馈DAC的多位ADAC非线性的数字校正。通过低分辨率校准ADC（CADC）估计多位ADAC的积分非线性（INL）误差（在线或离线）并存储在随机存取存储器（RAM）表中。然后，INL值用于补偿ADAC在数字域中的失真。当这种补偿与DWA等不匹配成形技术相结合时，可以显着放宽CADC的分辨率要求。所提出的用于误差反馈调制器的修正电路的实现本质上是简单的，因为校正仅需要数字求和而不需要任何额外的数字滤波。

摘要： The invention provides a communication protocol and serial interface having an approximately fixed interface clock and capable of accommodating a variety of communication rates. The interface employs a variable-length frame that may be expanded or reduced to obtain a desired communication rate, even though the interface clock rate is held approximately constant. The invention further provides a method for designing an agile barrier interface. In particular, the barrier clock rate is preferably selected to be an approximate common multiple of the various communication rates that the barrier interface must handle. The frame length corresponding to each communication rate may then be obtained by dividing the barrier clock rate by the ΣΔ rate. Finally, the invention provides an agile barrier capable of communicating data across a serial interface at a variety of data rates and at an approximately fixed interface clock rate.

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.

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.
