Abstract
The present invention is directed to an oscillator circuit comprising an oscillator input for providing an input signal, a first integrator circuit comprising a first integrator capacitor and a first integrator output, a comparator, a discharge circuit for discharging said first integrator capacitor once per cycle of said oscillator circuit, and an oscillator output for providing an output signal, wherein said oscillator circuit further comprises a second integrator circuit comprising a second integrator capacitor and a second integrator output, and wherein said oscillator circuit is arranged for allowing said input signal to be subsequently integrated by said first and second integrator circuit in an alternating manner, and for providing said integrated output signal of said first and second integrator circuit subsequently to said comparator in said alternating manner.
