  • Integrated high-frequency MOS oscillator
    Patent number: 6897736
    Abstract: An integrated high-frequency MOS oscillator circuit comprising at least one active element (F1) and a frequency determining circuit, the oscillator circuit further comprising at least one frequency selective network (R1, C1) which is built up from one or more resistors and one or more reactive elements, such that the oscillation at the desired oscillator frequency can take place substantially unhampered, while oscillations at parasitic oscillation frequencies are suppressed in that at the parasitic oscillation frequencies the loop gain is reduced to an absolute value less than 1.
