摘要:
The invention relates to an active electrode to be used for non-invasive measurement of low-intensity biosignals on the body surface. According to the invention, the active electrode uses a differential input preamplifier made with a high-pass filter () and an instrumental amplifier (), the preamplifier output signal being passed through a band-pass active filter () and then applied to the input of another differential instrumental amplifier (), while, at the other input, there is applied the signal provided by a reference voltage generator () setting the reference level of the analogue channel for conditioning the biosignal to be measured the output of the instrumental amplifier () is applied through a low-pass filter () to the input of a programmable gain amplifier () whose output is applied to the input of an analogue-to-digital Sigma-Delta converter () and the data obtained at the output of this converter () are sent to a hierarchically superior module through a serial data channel () with two lines, the data line and the clock signal, through which the gain of the programmable gain amplifier () is also programmed.Invenţia se referă la un electrod activ utilizabil pentru măsurarea neinvazivă, de pe suprafaţa corpului, a biosemnalelor de mică intensitate. Electrodul activ, conform invenţiei, utilizează un preamplificator diferenţial de intrare, realizat cu un filtru trece sus () şi un amplificator instrumental (), semnalul de la ieşirea preamplificatorului este trecut printr-un filtru activ trece bandă (), apoi este aplicat unei intrări a unui alt amplificator instrumental diferenţial (), la cealaltă intrare fiind aplicat semnalul furnizat de un generator () de tensiune de referinţă, care stabileşte nivelul de referinţă al canalului analogic de condiţionare a biosemnalului măsurat ieşirea amplificatorului instrumental () este aplicată printr-un filtru trece jos () la intrarea unui amplificator cu câştig programabil (), a cărui ieşire este aplicată intrării unui c
