Abstract

An analog-to-digital converter (ADC) (10) includes a continuous time filter (14), a quantizer (18), a continuous time digital-to-analog converter (20), a discrete time DAC (24), and a switch (26). The quantizer (18) has an input terminal coupled to the output terminal of the continuous time filter (14), and a plurality of output terminals. The continuous time DAC (20) has a plurality of input terminals coupled to the plurality of output terminals of the quantizer (18), and an output terminal. The discrete time DAC (24) has a plurality of input terminals coupled to the plurality of output terminals of the quantizer (18), and an output terminal. The switch (26) has a first input terminal coupled to the output terminal of the continuous time DAC (20), a second input terminal coupled to the output terminal of the discrete time DAC (24), and an output terminal coupled to the input terminal of the continuous time filter (14).
