Claim:
1. A frequency generator comprising: a quantization circuit 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, wherein the phase transition at the quantized effective time instant is an output of the quantization circuit; a noise shaper circuit configured to provide a noise-shaped feedback signal using the desired time instant and the quantized effective time instant; and an error generator circuit configured to cause an error component within a time instant of a phase of a signal provided as an input to the quantizer circuit, wherein the error component is at least 50 per cent of a temporal quantization unit of the quantizer circuit, and wherein the error component is determined using a non-Gaussian and non-equally distributed error distribution.
