Abstract

Inventia se refera la un circuit de intrare pentru un receptor în infrarosu destinat sa prelucreze semnalele primite prin canalul de comunicatie optic de la emitatoarele în infrarosu cu drivere care utilizeaza surse de emisie necoerenta (LED în infrarosu), sau coerente (LED laser). Circuitul are în structura un fototranzistor, o rezistenta de polarizare, un repetor format dintr-un tranzistor cu elemente de polarizare conectat în alternativ la fototranzistor printr-un condensator sau în curent continuu printr-un rezistor, un comparator cu elemente de polarizare, un circuit monostabil cu elemente de temporizare, un amplificator format dintr-un circuit operational si un tranzistor cu elemente de polarizare si un LED cu emisie în infrarosu.The invention relates to an input circuit for an infrared receiver intended to process the signals received through the optical communication channel from the infrared emitters with drivers using incoherent (LED) or coherent (LED) emission sources. The circuit has a phototransistor, a polarization resistance, a repeater made up of a transistor with polarization elements connected in alternation to the phototransistor by a capacitor or DC through a resistor, a comparator with polarizing elements, a circuit monostable with timing elements, an amplifier consisting of an operational circuit and a transistor with polarizing elements and an infrared emitting LED.
