(FR) DISPOSITIF DE DÉTECTION MAGNÉTIQUE
(JA) 磁気検出装置
Abstract:
(EN) An amplification circuit (20) is provided with an operational amplifier (21) and a multiplexer (MUX). The multiplexer is provided with: n input nodes (N1 to Nn) into which output signals (V1 to Vn) from n magnetic detecting elements (E1 to En) are respectively input; an output node (NM) connected to an inverting input terminal (T1) of the operational amplifier; and n switching elements (S1 to Sn) provided respectively between the output node and the n input nodes. The amplification circuit is additionally provided with n-1 resistive elements (H1 to Hn-1) The n-1 resistive elements are provided respectively between each pair of adjacent input nodes from among the n input nodes, and each has a resistance value higher than the ON resistance of each switching element.
(FR) La présente invention concerne un circuit d'amplification (20) pourvu d'un amplificateur opérationnel (21) et d'un multiplexeur (MUX). Le multiplexeur comprend : n nœuds d'entrée (N1 à Nn) dans lesquels des signaux de sortie (V1 à Vn) en provenance de n éléments de détection magnétique (E1 à En) sont respectivement entrés ; un nœud de sortie (NM) connecté à une borne d'entrée inverseuse (T1) de l'amplificateur opérationnel ; et n éléments de commutation (S1 à Sn) disposés respectivement entre le nœud de sortie et les n nœuds d'entrée. Le circuit d'amplification est en outre pourvu de n-1 éléments résistifs (H1 à Hn-1). Les n-1 éléments résistifs sont disposés respectivement entre chaque paire de nœuds d'entrée adjacents parmi les n nœuds d'entrée, et chacun présente une valeur de résistance supérieure à la résistance ON de chaque élément de commutation.
(JA) 増幅回路(20)は、オペアンプ(21)と、マルチプレクサ(MUX)とを備える。マルチプレクサは、n個の磁気検出素子(E~E)の出力信号(V~V)がそれぞれ入力されるn個の入力ノード(N~N)と、オペアンプの反転入力端子(T1)に接続される出力ノード(NM)と、出力ノードとn個の入力ノードとの間にそれぞれ設けられるn個のスイッチング素子(S~S)とを備える。増幅回路は、さらに、n-1個の抵抗素子(H~Hn-1)を備える。n-1個の抵抗素子は、n個の入力ノードのうちの隣接する入力ノード間にそれぞれ設けられ、各スイッチング素子のオン抵抗よりも高い抵抗値を各々が有する。
