Abstract
The switched-capacitance amplifier comprises n capacitors C.sub.11 to C.sub.1n which are periodically switched in parallel and in series, the n parallel-switched capacitors being charged simultaneously by the same voltage V.sub.E. An amplified voltage n.times.V.sub.E is obtained between the end terminals A and B of the n series-switched capacitors. Periodic switching of the n capacitors in parallel and in series is performed by means of MOS transistors T.sub.11 to T.sub.1(2n-1) and T.sub.21 to T.sub.2(n-1) which operate in the switching mode. The n capacitors and the MOS transistors are integrated on the same semiconductor substrate.
