ABSTRACT:
An integrated variable resistor in MOS technology includes two parallel-connected transistors (T1, T2) whose electrodes are floating relative to the substrate (8). Its resistance is controlled by means of current sources (3, 4, 5, 6) whose current flows through the transistors (T3, T4) arranged as resistors. The body effect in the transistors (T1, T2) is compensated for by an equally large body effect in the transistors (T3, T4).
