Abstract
A driver circuit for voltage boosting comprises a plurality of circuit cells, each configured to amplify voltage applied thereto; and a plurality of inter-cell switching circuits, arranged to controllably concatenate the cells in series such that, for any pair of adjacent cells, voltage amplified by one cell of the pair is applied, via a respective inter-cell switching circuit, to another cell of the pair. At least one of the inter-cell switching circuits comprises a transistor and a capacitor connected in parallel to each other such that a source-gate voltage of the transistor equals a voltage drop on the capacitor at all times.
