PROBLEM TO BE SOLVED: To provide a system, method and technique for converting a continuous-time, continuously variable signal into a sampled and quantized signal.SOLUTION: An apparatus includes multiple quantization-noise-shaping continuous-time filters each in a separate processing branch and having an adder that includes multiple inputs and an output. An input signal is coupled to one of the inputs of the adder. The output of the adder is coupled to one of the inputs of the adder through a first filter. An output of a sampling/quantization circuit in the same processing branch is coupled to one of the inputs of the adder through a second filter having a different transfer function than the first filter. |
