  • Amplification circuit using wire-bonding for adjusting amplification factor
    Patent number: 5796310
    Abstract: An amplification circuit comprises an operational amplifier, an input resistance unit and a feedback resistance unit. The input resistance unit consists of a plurality of input resistances connected in series, and the feedback resistance unit consists of a plurality of feedback resistances connected in series. A plurality of adjusting pads are provided at respective connecting points of these input and feedback resistances. There is a common pad having an electrical potential fixed at a reference voltage. A first wire selectively bonds one of adjusting pads corresponding to the input resistances with the common pad to set a resistance value of the input resistance unit. And, a second wire selectively bonds one of adjusting pads corresponding to the feedback resistances with the common pad to set a resistance value of the feedback resistance unit.
