Abstract: A transimpedance amplifier includes a first and a second power supply terminal for receiving a positive constant supply voltage, wherein the second power supply terminal represents a ground, and an input terminal adapted to be connected to a current source. The transimpedance amplifier further comprises a transistor comprising a control terminal and two further terminals, wherein the input terminal is connected to the control terminal of the first transistor. An inductor is connected between the first of the two further terminals of the transistor and the first power supply terminal, and a bias network is connected between the second of the two further terminals of the transistor and ground. Specifically, the transimpedance amplifier is configured such that the resistance between said first of said two further terminals of said first transistor and said first power supply terminal is small enough, such that said transimpedance amplifier operates as a differentiator.

Abstract: A driver circuit may include a first node, and a first circuit to generate on the first node an inverted replica of an input signal during driver switching between a first supply voltage and a first reference voltage, the inverted replica having a threshold voltage value based upon a second reference voltage greater than the first supply voltage. The driver circuit may include a cascode stage to be controlled by the second reference voltage and to be coupled between a second supply voltage and the first node, a delay circuit to generate a delayed replica of the input signal, an amplifier, and a switching network to couple the control terminal of the active load transistor to one of the first reference voltage and the first node based upon the input signal.

Abstract: An electrical-optical modulator may function at high data rates and may be realized in comparably low cost silicon base technology, typically in BJT, BiCMOS or CMOS technologies. The output signal path may include a high transition frequency BJT and by using an active load constituted by a MOS driven by an inverted version of the modulating signal that drives the BJT, the falling edge of the output signal is sped up.

Abstract: A system for detecting objects, for driver assistance equipment in motor vehicles for example, includes a transmitter for transmitting towards an object an optical signal having a signal energy. The optical signal transmitted includes at least one encoded pulse sequence with the signal energy distributed over the pulse sequence. A receiver receives an echo signal resulting from reflection of the optical signal at the object with the time delay of the echo signal is indicative of the distance to the object.
