    Abstract: Optoelectronic component for converting electromagnetic radiation into an intensity-dependent photocurrent comprising a substrate formed in CMOS technology, in particular, with an integrated semiconductor structure (ASIC) and an optically active thin-film structure arranged upstream in the direction of light incidence and comprising in each case at least one layer made of doped and at least one layer made of undoped semiconductor material, which is connected to a microelectronic circuit arranged on the substrate by means of an insulating layer, within which are situated connecting means for contact-connecting the optically active thin-film structure to the semiconductor structure. The invention is based on the object of providing an optoelectronic component, and a method for fabricating it, which, on the one hand, can be fabricated more simply and, on the other hand, has a reduced dark current. This object is achieved according to the invention by virtue of the fact that the optically active thin-film structure has a layer sequence made of a metal and an intrinsically conducting amorphous or microcrystalline semiconductor material, in particular silicon and alloys thereof, which is applied directly to the planarized insulating layer.

    Abstract: A direct conversion receiver has a compensation module (MDM) envelope (PD2) and alternating signal (PD1) detectors with subtracter (CMP) and sampler (SAH) connected between the input (BE) from a conversion stage and output (STR) to a programmable gain amplifier (PGA) to create a compensation signal (SCP)

    Abstract: The pulse response estimation method has a first estimate (40) of the pulse response (H). The pulse response is corrected (41) for the first estimate independent of the information transmitted, using the transmitted and pulse response characteristics. A final corrected estimate (HF) of the channel response is then obtained.

    Abstract: A method for synthesizing a clock signal, said clock signal being locked to a reference clock signal, said method providing for using a third clock signal, operating at a higher frequency. The method provides the steps of: measuring the reference clock signal (CK_REF) by means of the third clock signal (CK_HIGH), operating at a higher frequency, obtaining a measured value (MES) of the reference clock signal (CK_REF) frequency; comparing the measured value (MES) with a nominal value; obtaining a correction value (CRR) as a function of the measured value (MES) and storing said correction value (CRR); using said correction value (CRR) for driving a digital controlled oscillator (OC) that outputs the synthesized clock signal (CK_SYN).
