  • Patent number: 9571397
    Abstract: A method of transmitting data allows flow control information to be transmitted with the user data over a synchronous bus. A channel is defined, identifying the source and at least one sink, and this includes the definition of a transport profile, indicating a flow control requirement for the data. Data is then transmitted from the source over the bus in at least one data time slot (30) and, if indicated by the transport profile, flow control information is also transmitted from the source over the bus in at least one flow control time slot (20) associated with the data time slot.

  • Patent number: 7872517
    Abstract: Clock control is handed over in a bus circuit from a first circuit (14) to a second circuit (12). A clock conductor (10a) is driven to a predetermined voltage level with the driver circuit of the first circuit after a last clock period following the start of execution of the handover command and to continue driving the clock conductor (10a) to the predetermined voltage level for a first time-interval. The clock conductor (10a) is driven to the predetermined voltage level with the driver circuit of the second circuit after a second time interval following the start of execution of the handover command until a third time interval has elapsed following the end of the second time interval. Subsequently the clock conductor (10a) is driven under control of the clock circuit (140) of the second circuit (14).

  • Publication number: 20070262821
    Abstract: The invention relates to a method for increasing the sensitivity of a chain of amplifiers that comprises the steps of amplifying a signal by means of a first amplifier with a gain factor A1=A1,m*?A1, where A1,m denotes a constant gain factor and ?A1 denotes a gain factor variation with 1??A1,min??A1??A1,max, further amplifying the signal by means of a second amplifier with a controllable gain factor A2?A2,max, where variations ?A1 of the gain of the first amplifier are compensated by reducing the gain A2 of the second amplifier, so that the difference between the chain gain factor AC=A1*A2 and a target chain gain factor AT?AT,max becomes zero.
