Abstract: Embodiments relate to a frequency generator. The frequency generator comprises a quantization device configured to synthesize a carrier signal with a desired frequency characterized by a series of phase transitions at desired time instants, by approximating a phase transition at a desired time instant with a phase transition at a quantized effective time instant. The frequency generator further comprises a noise shaper configured to provide a noise-shaped feedback signal using the desired time instant and the effective time instant. Moreover, the frequency generator comprises an error generator configured to cause an error component within the effective time instant, the error component being at least 50 percent of a temporal quantization unit.

Abstract translation: 实施例涉及频率发生器。 频率发生器包括量化器件，其被配置为通过在期望的时刻通过在量化的有效时刻的相变近似相移来以合成具有以期望的时刻在一系列相变为特征的期望频率的载波信号。 频率发生器还包括噪声整形器，其被配置为使用期望的时刻和有效时刻来提供噪声形状的反馈信号。 此外，频率发生器包括误差发生器，其被配置为在有效时刻内产生误差分量，误差分量为时间量化单元的至少50％。
