Patent ID: 8461909

Claim:
A voltage booster device comprising: a plurality of multiplication stages arranged in a sequence, each having an input terminal coupled to an output terminal of a next multiplication stage with the exception of a first multiplication stage and each of the plurality of multiplication stages comprising pumping circuitry configured to accumulate an electric charge based upon a pump voltage value of the multiplication stage; said pumping circuitry in at least one of said plurality of multiplication stages comprising a plurality of charge accumulators coupled in series, a terminal between said plurality of charge accumulators, and biasing circuitry coupling the terminal to an output terminal of a previous multiplication stage in the sequence and configured to force operation of said plurality of charge accumulators within a threshold potential drop value; and a phase signal generation circuit configured to switch operation of the plurality of multiplication stages between a transfer phase and a maintaining phase such that multiplication stages located in an even position in the sequence operate in the transfer phase when multiplication stages located in an odd position in the sequence operate in the maintaining phase, and vice-versa.
