摘要:
A driver circuit which has one or more driver transistors connected to a load and which further includes at least one circuit block configured to control the voltage on the gate nodes of the one or more driver transistors and which is connected to the latter. The gate source voltage of the one or more driver transistors can be controlled, using an appropriate configuration of the circuit blocks in relation to the circuit, by the application of the current in such a way that the charging/discharging current is approximately sine2. The circuit block has a current source that controls the gate voltage on the gate nodes of the one or more driver transistors and the circuit block as an additional first voltage source that provides the operating voltage of the driver circuit, in addition to a second voltage source that provides a control voltage which is used to adapt the driver circuit to different load magnitudes.

The invention relates to a driver circuit (10) for integrated circuits comprising at least one input node (11) for an input signal and at least one output node (12) for an output signal. One or several, preferably two partial drivers (20, 30) supply approximately sine-wave shaped current to the load capacity (15) thereby improving electromagnetic compatibility. A feedback circuit (40) is also provided. Said feedback circuit consists of one or several evaluation circuits (50) and one or several feedback capacitors (41). The evaluation circuits (50) are connected to the partial drivers (20, 30) One feedback capacitor (41, 42) is respectively arranged between an output node (12) of the driver circuit (10) and an input node (51) of an evaluation circuit (50). An evaluation circuit (50) is provided via the feedback condenser (41, 42) between an output node (12) of the driver circuit and an input node (51). The edge steepness of the signal i.e. current which is independent of the actual load, can be produced by means of a feedback circuit (40). The feedback capacitor (41) can, for example, be embodied as a non-linear capacitor.

The invention relates to an arrangement (10) and a method for adjusting the slope times of one or more drivers (90) in such a way that the adjustment is essentially independent of external conditions. The invention also relates to a driver circuit. The arrangement (10) is provided with a device (20) for detecting the time history of an output voltage that is output and supplied to a load (12) by means of the driver/s (90). The measured time values are converted into an output voltage value in a device (36) for converting the measured time history of the output voltage. Moreover, a device (40) for generating a reference voltage value is provided. The device (40) is connected to a device (60) for predetermining a desired slope time for the driver/s (90), whereby the slope time is essentially independent of external conditions. A system pulse can be partitioned into differently long rectangular pulses in the device (60) in such a way that the user of the arrangement (10) can select from the group of the rectangular pulses which match certain slope times respectively. The output voltage value and the reference voltage value are compared in a comparing device (50) that is also connected to the driver/s (90) in such a way that the driver/s (90) can be readjusted thereby.

Customary applicators for water-jet surgery comprise a handle, a pressure conduit to supply a working fluid from a pressure source and a nozzle at the end of the pressure conduit to generate a fluid jet with specified properties. It is now proposed to provide a set of molded parts that differ from one another in size and/or shape, that can be detachably, individually connected to the handle to form guide devices to guide the elastically deformable pressure conduit from the handle to the nozzle along a course predetermined by the relevant molded part.

摘要:
A circuit configuration for processing data, particularly a semiconductor memory chip, has a control circuit for setting a phase or frequency relationship between two signals. A digital counter detects a phase or frequency difference between the two signals, and the counter reading is used for regulating the phase or frequency relationship. Trials have shown that the counter reading indicates an operating state in the circuit configuration and therefore represents a simple signal for assessing the operating state of the circuit configuration. Preferably, the counter reading is taken as a basis for adjusting the speed or power of time-critical or performance-critical circuit parts in the circuit configuration so that an operating state with an intermediate switching speed is obtained.
