Abstract
An integrated oscillator circuit (16) with an amplifier circuit (22) and a frequency-selective feedback network comprising a first resonant circuit (18) and a second resonant circuit (20) is proposed. The oscillator circuit is characterized in that the first resonant circuit (18) is connected to the amplifier circuit (22) solely on the output side and is formed as a parallel resonant circuit comprising a first capacitor (24) and a first inductor (26), and the second resonant circuit (20) is connected to the amplifier circuit (22) solely on the input side (36, 38) and is formed as a parallel resonant circuit comprising a second capacitor (32) and a second inductor (34).
