摘要： Techniques for controlling a driver to reduce data dependent noise, such as simultaneous switching effects and cross-talk effects. A plurality of drivers may each receive a data segment to transmit and a plurality of data segments that other drivers will transmit. A driver controller may adjust the time at which the data segment is transmitted in response to the plurality of data segments that the other drivers will transmit. The adjustment may compensate for simultaneous switching noise and cross-talk by, for example, delaying the transmission of a data segment or changing the slew rate of the signal carrying the data segment.

摘要： A multiple supply voltage device includes an input/output (I/O) network operative at a first supply voltage, a core network coupled to the I/O network and operative at a second supply voltage, and a power-on-control (POC) network coupled to the I/O network and the core network. The POC network is configured to transmit a POC signal to the I/O network and includes an adjustable current power up/down detector configured to detect a power state of the core network. The POC network also includes processing circuitry coupled to the adjustable current power up/down detector and configured to process the power state into the POC signal, and one or more feedback circuits. For reducing the leakage current while also improving the power-up/down detection speed, the feedback circuit(s) are coupled to the adjustable current power up/down detector and configured to provide feedback signals to adjust a current capacity of the adjustable current power up/down detector.

摘要： Systems and methods for circuits that self-correct errors due to variations in fabrication processes, voltages, and temperature (PVT), as well as input timing errors. In an exemplary embodiment, a method for improving output signal quality in a complementary logic circuit is provided. An n-type transistor in the complementary logic circuit is digitally enabled or biased with a first variable power supply. A p-type transistor in the complementary logic circuit is digitally enabled or biased with a second variable power supply, providing a voltage different from that of the first variable power supply, to mitigate a difference in the switching times between the p-type transistor and the n-type transistor.
