An amplifier circuit for an oscillator in a defined oscillating frequency range includes a plurality of transconductors, wherein at least one transconductor has a positive transconductance, and wherein at least one other transconductor has a negative transconductance, wherein the transconductors together provide a positive amplification, and a passive impedance element coupled to at least one fed back transconductor, wherein the transconductance of the transconductor and the impedance element are dimensioned so that, in the oscillating frequency range, a given phase difference is present between a signal at the input and a signal at the output.
