| 摘要 |
Time-continuous sigma/delta analog-to-digital converter for converting an analog input signal into a digital output signal (D), having at least one analog filter ( 3 ) which filters the analog input signal present at a signal input ( 2 ) of the analog filter ( 3 ), a quantizer ( 12 ) which is clocked by a clock signal (CLK) and quantizes the filtered analog signal, output by the analog filter ( 3 ), in order to generate the digital output signal (D), and having at least one reference capacitor ( 28 ) which can be continuously charged to a reference voltage (V<SUB>REF</SUB>) by a current source ( 31 ) for displacing a constant charge (Q) to/from the analog filter ( 3 ), such that no voltage jumps occur at the analog filter ( 3 ).
