摘要: Methods and apparatus are described for converting a digital data stream to an analog signal. Charge is added to and subtracted from an input of an integrator in a manner representative of the digital data stream thereby generating the analog signal at an output of the integrator. The amount of charge is varied thereby controlling the output level of the analog signal.

摘要: A variety of methods and arrangements for improving the fuel efficiency of internal combustion engines are described. In some aspects, methods and arrangements are described for operating an engine in a throttled skip fire mode. In other aspects, methods and arrangements are described for controlling the operational state of a variable displacement engine.
