Abstract
There is described a hybrid ADC device for converting an analog input signal (Vin) into a digital output signal (Vout), the device comprising a first ADC circuit configured to receive the analog input signal (Vin) and convert it into a first digital signal (Y); a DAC circuit configured to receive the first digital signal and convert it into a first analog signal; a delay circuit configured to delay the analog input signal; a first combiner configured to generate an analog residual signal by subtracting the first analog signal from the delayed analog input signal; a second ADC circuit configured to receive the residual analog signal and convert it into a second digital signal (Y); a filter circuit configured to receive the first digital signal and output a filtered first digital signal (Y′), the filter circuit having a transfer function corresponding to a combined transfer function of the DAC circuit and the second ADC circuit; and a second combiner configured to generate the digital output signal (Vout) by adding the second digital signal and the filtered first digital signal, wherein the first ADC circuit comprises an anti-aliasing filter. Furthermore, a corresponding method and an automobile radar system are described.
