摘要： A receiver circuit is disclosed which enables a reception signal fed into the receiver circuit by a reception element to be processed—e.g. amplified—with little to no errors. The receiver circuit has a cascode circuit on an input side, which cascode circuit generates an output signal from the reception signal of the reception element. Control means that act on the cascode circuit are connected to the cascode circuit. The control means are configured in such a way that they counteract an increase in a high level of the output signal of the cascode circuit on account of an excessively large input signal from the reception element.

摘要： An electronic driver circuit for a directly modulated semiconductor laser has a first circuit for generating a constant current and second circuit for modulating the constant current in dependence on a digital data signal. The modulated current forms a laser current that drives the semiconductor laser. An optimal signal shape of the modulated current is guaranteed to the greatest possible extent, even in the case of high modulation frequencies above one Gbit/s, by way of a third circuit that is connected in parallel with the semiconductor laser. The third circuit acts as an ohmic resistance with a high impedance for direct current and with a low-impedance for alternating current with the modulation frequency.

摘要： A temperature sensor has a first FET transistor circuit, whose operating point is located at the temperature-independent point, and a second FET transistor circuit whose operating point is above this point. The voltage difference in this case depends essentially linearly on the temperature. In addition, a circuit for controlling the gain of an amplifier circuit is provided, in which the current through the amplifier circuit at low temperatures is reduced by an appropriate control of the gate voltage of a transistor serving as a current source, so that an amplification which is substantially independent of temperature is carried out.

摘要： The device and method compensate for propagation differences between n serial data streams each transmitted over parallel optical lines. Data that can be transmitted via the n serial data streams are configured as m-bit words. The device has n regeneration devices in which data of the data stream can be regenerated. A data output and a clock pulse output of the regeneration devices are connected to a propagation time control device so that the regenerated data and the regenerated clock pulse can be transmitted to a data input or to a clock pulse input of the propagation time control devices. The propagation time control devices each have a demultiplexer for dividing the regenerated data as well as the regenerated clock pulses with a ratio of 1:(x·m), and each have an alignment device for distributing the divided regenerated data on x·m parallel data outputs of the propagation time control devices.

摘要： The circuit has a push-pull end stage which acts as an amplifier stage for digital signals. The push-pull end stage has two n-channel MOS transistors which function as source followers and two p-channel MOS transistors which also function as source followers. The gate terminals of the respective n-channel MOS transistors and p-channel MOS transistors are each controlled by an operational amplifier through drivers. A voltage that determines the setpoint value of the high level of the output of the push-pull end stage is present at the non-inverting input of one operational amplifier and a voltage that determines the low level of the output of the push-pull end stage is present at the inverting input of the other operational amplifier. The operational amplifiers interact with feedback elements in such a way that the high level or the low level of the gate voltages of the n-channel and p-channel transistors are controlled at an essentially constant value independently of the operating state of the push-pull end stage.

摘要： The invention relates to an optical duplex connector which has two optical waveguides, a connector housing, in which the optical waveguides are arranged with a defined lateral spacing in relation to each other, and a triggering mechanism for locking and/or unlocking the optical connector with respect to a coupling partner. The triggering mechanism comprises at least one interacting part, which interacts with at least one corresponding part of the coupling partner for locking and/or unlocking. In this case, the at least one interacting part is arranged, with respect to the plugging direction, in the lateral region between the two optical waveguides or extends along this lateral region. This leads to a particularly compact connector structure.

摘要： An electronic driver circuit for directly modulated semiconductor lasers is described. The drive circuit has a first circuit for generating a constant current and a second circuit for modulating the constant current. The second circuit generates, as a function of a digital data signal, a modulation current that is superimposed on the constant current, the modulated current being fed to a semiconductor laser. According to the invention, a third circuit is additionally provided which keeps the driver circuit at a low impedance during a rising edge and/or a falling edge of the current through the semiconductor laser. As a result, the signal shape of the optical output signals of the semiconductor laser can be improved, and the driver circuit can be operated at higher data rates, in particular at data rates of up to 12 Gbit/s.
