Abstract
Temperature-stabilized oscillator circuit A temperature-stabilized oscillator circuit (1) comprises a first part with a first temperature dependence and a second part with a second temperature dependence, which is different from the first temperature dependence. A charge storage device (C2), a controllable upward-integration current source (T2) for charging the charge storage device (C2), a controllable downward-integration current source (TB3) for discharging the charge storage device (C2) and two resistors (R2, R1) having the same temperature coefficients are contained in each case in one of the two parts.
