Abstract

The present invention relates to an oscillator circuit and a method for tuning an oscillation frequency, wherein transistors of a pair of emitter followers are coupled via at least one inductor, and a reverse tuning voltage is applied to a collector-base junction of at least one transistor of the pair of emitter followers in order to tune the oscillation frequency by controlling the collector-base capacitance of the at least one transistor. Thereby, varactorless tuning of an oscillation frequency can be achieved.
