Abstract
The present disclosure relates to parametric amplifiers that can be used in the presence of a magnetic field. In particular the present disclosure relates to an integrated signal amplifier that comprises: a quantum dot; a first conductive electrode arranged in a manner such that tunnelling of electrons to the quantum dot is prevented; and a second conductive electrode arranged in a manner such tunnelling of electrons to the quantum dot is permitted. When an oscillating signal is applied across the first and second electrodes, the equivalent capacitance across the first and the second electrodes oscillates at the frequency of the oscillating signal.
