1. An analog-to-digital converter (ADC) comprising:
a first conversion stage having a residue output;
an amplifier having an input selectively coupled to the residue output of the first conversion stage;
a second conversion stage having an input selectively coupled to an output of the amplifier; and
a switched-capacitor network having a first port coupled to the input of the amplifier and having a second port coupled to the input of the second conversion stage, the switched-capacitor network being configured to provide a second-order or higher noise transfer function for noise shaping of quantization noise of the second conversion stage.
