A differential output is provided from a single-ended input by a switch-capacitor stage having a through-switched capacitor (12) coupled via an amplifier (7) to one output terminal (1) and a diagonally-switched capacitor (12) coupled via an amplifier (7) to another output terminal (2). Each amplifier (7) is provided with a through-switched negative feedback capacitor (9). A delay inherent in the switching of the diagonally-switched capacitor (12) provides an interpolation effect in the differential output. |
