Abstract
A hybrid analog-to-digital converter includes a plurality of converting circuits. Each converting circuit is configured to provide a digital signal based on an analog input signal by performing a successive approximation conversion to obtain, as a result of the successive approximation conversion, a first number of bits of the digital signal, and by subsequently performing a slope conversion based on a common variable reference voltage to obtain a second number of bits of the digital signal, the second number of bits corresponding to a residual between the analog input signal and the result of the successive approximation conversion. The hybrid analog-to-digital converter further includes a common variable reference voltage provider configured to provide to each converting circuit of the plurality of converting circuits the common variable reference voltage.
