Abstract
The oscillator circuit comprises first and second integrator units with a first capacitor charged at a first integration node and a second capacitor charged at a second integration node. A comparator unit is arranged between a first switching unit, which is connected to the integration nodes and to a reference signal (VREF), and a second switching unit. The comparator unit compares a signal from the first or second integration node with the reference signal. The second switching unit is connected to a logic unit configured to provide signals controlling the first integrator unit, the second integrator unit, the first switching unit and the second switching unit, so that a periodic operation is generated by alternatingly activating the first integrator unit and the second integrator unit.
