Circuit with two digital-to-analog converters and method of operating such the circuit

A pipeline converter circuit comprising

• a first stage that includes a first input configured to receive a first stage input signal, a first output configured to produce a first stage output signal, and a first digital-to-analog converter coupled between the first input and the first output, wherein the first digital-to-analog converter is configured to receive a first digital signal derived from the first stage input signal, and to produce a first analog signal from which the first stage output signal is derived;
• a second stage that includes a second input coupled to the first output and configured to receive the first stage output signal, a second output configured to produce a second stage output signal, and a second digital-to-analog converter coupled between the second input and the second output, wherein the second digital-to-analog converter is configured to receive a second digital signal derived from the first stage output signal, and to produce a second analog signal from which the second stage output signal is derived;
• a plurality of unit elements;
• and
• switching circuitry coupled to the first and second stages and to the plurality of unit elements, wherein the switching circuitry is adapted so that, in a first switching state, a set of unit elements of the plurality of unit elements forms part of the first digital-to-analog converter, and in a second switching state, the set of unit elements forms part of the second digital-to-analog converter, wherein the set of unit elements includes fewer than all of the unit elements in the plurality of unit elements.
