An output buffer for an oscillator circuit and associated methodology. The output buffer has inverters and at least one negative feedback loop coupled to corresponding inverters. The negative feedback loop of the circuit is disabled in response to a control signal until one or more of a defined level of oscillation and a defined period of time is reached during start-up of the oscillator circuit, and is thereafter enabled. At least one of the inverters has at least one second negative feedback loop coupled to the corresponding inverter. An amount of feedback provided by the second negative feedback loop is adjustable in response to a control signal, where a first feedback level is present until a defined level of oscillation and/or a defined period of time is reached during start-up, a second feedback level is thereafter present in, and the first feedback level is less than the second feedback level.
