摘要： An integrated circuit has a synchronous circuit and an asynchronous circuit. A clock-controlled input register circuit and an output register circuit for storing data are each connected to the synchronous circuit and the asynchronous circuit. Data are transferred from the synchronous circuit into the input register circuit, from where they are transferred into the asynchronous circuit and processed in the asynchronous circuit. Processed data are transferred into the output register circuit. A sequence controller generates a respective control clock signal for the register circuits in a manner dependent on the data processing duration of the asynchronous circuit. This enables a high data throughput between the synchronous circuit and the asynchronous circuit independently of a clock frequency of the synchronous circuit.

摘要： An integrated semiconductor memory device includes a first input amplifier which, compared with a second input amplifier, has a lower sensitivity with regard to level fluctuations of its respective input signal. A control circuit drives a controllable switch in such a way that when a noisy clock signal is applied to the integrated semiconductor memory device, the less sensitive input amplifier is used for generating an internal clock signal. If, by contrast, a lower-noise clock signal is applied to the integrated semiconductor memory device, the control circuit drives the controllable switch in such a way that the more sensitive input amplifier is used for generating the internal clock signal. The changeover of the controllable switch is effected after evaluation of a bit sequence applied to a further input terminal of the integrated semiconductor memory device.

摘要： An electronic circuit for generating an output voltage has a defined temperature dependence, a bandgap circuit for generating a defined temperature-constant voltage and a temperature-dependent current with a defined temperature dependence, and a conversion circuit for generating the output voltage from the temperature-dependent current and the temperature-constant voltage. The conversion circuit has a first resistor at whose first terminal the temperature-constant voltage is applied, and whose second terminal is connected to a first terminal of a second resistor. The second terminal of the second resistor is connected to a supply voltage potential, and a first terminal of a third resistor is connected to the second terminal of the first resistor. The temperature-dependent current is supplied to a second terminal of the third resistor, and it being possible to tap the output voltage at the second terminal of the third resistor.

摘要： A chip card includes a semiconductor chip that contains at least one memory. In order to supply energy to the chip and to provide for bi-directional data transmission from and to the chip, both contacts and a device for contactless data transmission are provided. A triggerable switch device which is provided on the chip connects the memory either to the contacts or to the device for contactless data transmission as a function of a state of an output signal of a logic circuit connected to at least a voltage supply contact. The switch device assumes a position of repose when it is not triggered and in that position it connects the memory to the device for contactless data transmission, while only upon application of a voltage to the supply voltage contact, triggered by the logic circuit, does it connect the contacts to the memory.

摘要： A circuit configuration contains a flow controller that can be put into a plurality of states and outputs a respective command, in a respective one of the states, to a circuit component to be controlled. The flow controller has at least one asynchronously operating delay circuit via which the flow controller moves from one of the states into the respective next state. The delay circuit has a further signal path connected in parallel with it which contains a clock-controlled multivibrator. The delay circuit and the further signal path are able to be operated alternatively using a switching device. The circuit allows, particularly in integrated memories, an asynchronous access command sequence, in a first mode, and a synchronous access command sequence, in a second mode, to be produced for the flow controller, particularly in communication with a test unit.
