ELECTRONIC CIRCUIT AND MANUFACTURING METHOD FOR ELECTRONIC CIRCUIT

摘要

The conductance of an electronic circuit comprising a first electronic component having a nominal conductance with a given inaccuracy, said circuit comprising at least one additional field effect transistor connected in parallel with the component, may be adjusted. The sources of all field effect transistor are connected to a common source, the drains of all field effect transistor are connected to a common drain and a control unit controls the gate voltage of each field effect transistor individually. Preferably, the gate voltage is controlled by connecting the gate voltage of each field effect transistor either to a common gate or to the common source. The component may be used to form switches or amplifiers, or to control the conductance of circuits comprising other electronic components serially connected with the electronic circuit according to the invention.
