    Abstract: A new and advanced PWM current control is provided by a new method and control system architecture that achieve the very high performances of an advanced current control for full-bridge stages, in terms of accuracy, error, speed and frequency response, but with an outstandingly reduced complexity in terms of analog circuits required, comparable with that of an elementary peak current control. The only analog blocks required are one current sense transducer (i.e. a series resistor or a sense-FET) and one comparator for the current sensing while the rest of the control circuitry is digital.

    Abstract: An electronic synchronous/asynchronous transceiver device for power line communication networks is integrated into a single chip and operates from a single supply voltage. The transceiver device includes: at least an internal register that is programmable through a synchronous serial interface; at least a line driver for a two-way network communication over power lines implemented by a single ended power amplifier with direct accessible input and output lines that is part of a tunable active filter for the transmission path; and at least a couple of linear regulators for powering with different voltage levels different kind of external controllers linked to the transceiver device.
