Abstract
An apparatus for compensating for a quantization error has a time detector circuit for detecting a time signal on the basis of the number of clock signals occurring within the period of such time signal, a quantization error detector circuit for generating a quantization error time signal corresponding to a time difference between the time signal and the clock signal and being in the form of an analog voltage value, and a compensator circuit for compensating a digital detected time derived from the time detector circuit on the basis of an analog quantization error time from the quantization error detector circuit.
