Abstract
In an embodiment an oscillator circuit comprises a first integrator-comparator unit, a second integrator-comparator unit, and a logic circuit. The first integrator-comparator unit is prepared to provide a first signal as a function of a first integration of a first charging current and a subsequent comparison of a first integration signal resulting from the first integration with a reference signal. The second integrator-comparator unit is prepared to provide a third signal as a function of a second integration of a second charging current and a subsequent comparison of a second integration signal resulting from the second integration with the reference signal. The logic circuit is adapted to provide a clock signal, a first and a second measurement signal for respectively controlling the first and the second integrator-comparator unit.
