摘要： A cable driver (301) for driving a single ended transmission medium such as a coaxial cable (115) comprising a core (120) and a shield (121) comprises a differential driver (104, 377) comprising a first output (151) for putting a first signal to the core (120) of the single ended transmission medium (115), a second output (152) for putting a second signal to the shield (121) of the single ended transmission medium (115) through a termination resistor (118) having an impedance close to the characteristic impedance (Z0) of the single ended transmission medium (115), and a third output (153) for putting a transmit ground supply signal (GNDT), local to the differential driver, to the shield (121) of the single ended transmission medium (115) through a first high frequency low impedance path (112). In use, the current through the third output (153) will be substantially the inverse of the common mode current through the first and second outputs (151, 152). Hence both the common mode current and its inverse are provided to the single ended transmission medium (115). They cancel each other out and thus advantageously low EMI emissions occur.

The device comprises a first and second peak detector for detecting peaks in the differential digital data stream, a memory element for storing an average of the first and second detected peak signals during rich data patterns, an error signal selector for error signal selection, and a regulator for negative feedback of a selected error signal. The selected error signal is either the average of the detected peak signals stored on the memory element minus the signal at the output of the first peak detector, or the signal at the output of the second peak detector minus the average of the detected peak signals stored on the memory element.

摘要： A method for measuring time of flight of radiation includes emitting modulated radiation (51) in response to a first modulation signal, projecting the modulated radiation (51) onto a scene (55), and receiving radiation, the received radiation including at least modulated radiation reflected by the scene (55). The received radiation (26, 27) is converted into a radiation induced electrical signal. The radiation induced electrical signal is mixed with a second modulation signal, thus generating a mixed signal, which is integrated, thus generating an integrated signal. When the integrated signal exceeds a threshold value (Vref), charge is injected into the integrated signal. The method includes applying changes to the first and/or second modulation signal at one or more moments in time, and measuring the integrated signal at one or more moments in time, thus obtaining at least one TOF pair difference signal (62). The measuring includes using a single detector node (38) and associated memory element (25), to obtain a TOF pair difference signal (62). The method furthermore includes using one or more TOF pair difference signals to determine time of flight of radiation.

摘要： A multistage equalizer filter for compensating a received distorted signal having an amplitude for frequency dependent signal modifications introduced by a transmission channel includes at least one amplifying compensation stage having a gain and a saturation level, the gain being monotonically rising for at least a last decade in frequency below an upper data frequency of the received signal, and a gain control device for controlling the gain of the amplifying compensation stage such that the amplitude of the received signal amplified in the at least one amplifying compensation stage remains below the saturation level of the amplifying compensation stage. The gain may be regulated by separately regulating low frequency gain, mid-frequency gain and higher frequency gain for each of the at least one amplifying compensation stages.

摘要： The present invention relates to a novel photo-detector structure and method whereby light is detected in a semiconductor substrate. Through the use of a small current of majority carriers an electrical field is created that directs photo-generated minority carriers towards a detection region. In this way, a large sensitive area 34 for a detector can be designed with a detection region having low junction area and low associated detector capacitance, thus enhancing output signal to noise ratio and/or speed of attached readout circuits. Simultaneously, the assistant majority current can sweep the minority carriers from deep within the substrate towards the detection region, thus improving the overall detector sensitivity. By making the majority current reconfigurable, a photonic mixer structure with two or more detection regions can be conceived, whereby the direction of the applied current will determine in an efficient way to which detection region the photo-generated minority carriers will be directed. In this way, incident modulated light can get demodulated, such that phase and amplitude of the modulated light can be measured for a.o. range-finding applications.
