Electronic circuit and manufacturing method for electronic circuit

摘要

The conductance may be adjusted of an electronic circuit including a first electronic component having a nominal conductance with a given inaccuracy. The circuit includes at least one additional field effect transistor connected in parallel with the component. The sources of all field effect transistors are connected to a common source, the drains of all field effect transistors are connected to a common drain, and a control unit controls the gate voltage of each field effect transistor individually. 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 including other electronic components serially connected with the electronic circuit.
