Sigma-delta modulator having a clocked delay line

A sigma-delta modulator comprising

• a plurality of components operating in a time continuous manner,
• a filter for noise shaping comprising at least one clocked delay line,
• and a clocked comparator, wherein the delay line is a continuous-amplitude line and the comparator and the delay line are clocked with a common clock signal.

A sigma-delta modulator comprising:

• a clocked comparator clocked by a first clock signal, and
• a plurality of components operating in a time continuous manner,
• a filter for noise shaping, wherein the filter comprises at least one delay line, and wherein the delay line is a clocked line clocked by a second clock signal which is higher than the first clock signal.

A sigma-delta modulator comprising

• a plurality of components operating in a time continuous manner,
• a filter for noise shaping, wherein the filter comprises a component operating in a time continuous manner and at least one clocked delay line, wherein the plurality of components and the filter form a cascaded converter,
• wherein the modulator comprises a clocked comparator and is designed in such a manner that the delay line(s) is/are clocked at a clock rate which is higher than the comparator clock rate.
