摘要： An electric circuit (3) for trimming a resistance of a resistor (Rfix) comprises a current path (100) including a first section (110) and at least one second section (150), wherein the first and the at least one second section (110, 150) are connected in series in the current path (100). The first section (110) of the current path includes the resistor (Rfix) to be trimmed. The at least one second section (150) of the current path (100) includes a first current branch (151) and a second current branch (152). The first current branch (151) of the at least one second section (150) of the current path (100) includes a first trimming resistor (R150a) and a second trimming resistor (R150b) being connected in parallel. The second current branch (152) of the at least one second section (150) of the current path (100) includes a third trimming resistor (R150c) and a fourth trimming resistor (R150d) being connected in parallel.

摘要： Reference circuit arrangement according to this invention comprises a branched current path (BE) connecting a first and second terminal (T+, T-) via an intermediate terminal (TN). The intermediate terminal (TN) is connected to a reference terminal (GND). A current path (PTAT) is coupled between the first and second terminal (T+, T-) via the reference terminal (GND). A feedback loop (FB) is connected to the first and second terminal (T+, T-) and designed to control, at the first and second terminal (T+, T-), a virtual ground potential. A reference path (REF) is connected to the feedback loop (FB) having a reference input for receiving from the feedback loop a reference current (Iref) and reference output (Vref) to provide a reference voltage.
