Patent DE-19906860-A1 (DE)
Inventor: BAREITHER JUERGEN
IPC: H03K19/094
Filed: 1999-02-18
Abstract: A tristate differential output stage containing two parallel circuit branches, each with two series-connected field effect transistors (12, 14) and (16, 18) of different conduction type. The gates of the field effect transistors of the same conduction type in both circuit branches are each interconnected. The two field effect transistors (12, 16) can be put into either the on state or the off state by means of a control signal. When both field effect transistors (12, 16) of the same conduction type are in the off state, the output stage will be in the Z state. When switching over into the active state, a reference voltage is applied by means of a further switch to the interconnected gates of both field effect transistors of the same conduction type, which puts the two transistors into the on state, whereby a discharge circuit serves to discharge the gate capacitance of the two field effect transistors (12, 16) of the same conduction type during the switch-over process from the Z state into the on state, so that the switch-over process will be correspondingly fast. The output stage is capable of achieving high operational speeds, and it can be realised by using components of small dimensions which occupy little space within an integrated circuit. It is also distinguished by the fact that only little common mode noise occurs. <IMAGE>
Patent DE-19907729-A1 (DE)
Inventor: SPERSCHNEIDER RALPH
IPC: H04B1/66
Filed: 1999-02-23
Abstract: The invention relates to a method for generating a data flow from variable-length code words which are subdivided into a number of code word sets, whereby a raster comprising segments is determined for the data flow in which two adjacent raster points (41, 42) define a segment (40). The code words (1-6) from the first set are written into the data flow, beginning at raster points. Code words from the second set are then written into the data flow according to a predetermined allocation specification, whereby each code word from the second set is allocated to a separate segment. Whole code words or portions of code words which cannot be written according to their allocation are saved and entered into the data flow in additional writing attempts, whereby the allocation according to a predetermined specification is changed from one attempt to the next. This procedure is repeated in a similar manner for any additional data set that may exist. In this way, the ends of code words from the second set are decoupled from the beginnings of following code words from the second set, as the corresponding code words in a set are written in a segment by segment manner. This reduces the propagation of errors.
