Abstract
The present invention relates to an oscillator circuit, comprising a switched capacitor circuit comprising a parallel circuit with a current input to be supplied with a reference current on one side and being connected to a reference terminal on the other side. The parallel circuit further comprises a first capacitor in a first branch and, in a second branch, a second capacitor connected in-between a first and second switch. A switch control unit comprises a first input coupled to the current input of the parallel circuit and a second input to be supplied with a reference voltage as well as an oscillator output for providing an oscillator signal. The switch control unit is being designed to operate the first and second switch such that, in a charging phase, the first and second capacitor is charged to a respective level depending on the reference voltage and, in a discharging phase, the charge stored on the first capacitor is discharged using the charge stored on the second capacitor.
