Abstract

PURPOSE: To obtain a plurality of boosted voltages, by varying the number of boosting stages in a booster circuit.
CONSTITUTION: A charge pump type booster circuit is constituted with N-channel transistor(Tr) No-Nn and capacitors C1∼Cn, and when drain voltage of Tr is boosted through clock signals ϕ1, ϕ1' and a capacitor C, charges are transferred sequentially to next stage Tr to produce a higher voltage than a source voltage VDD at the output end. NAND gates 1, 2 and inverters 3, 4 are provided, and control signals are fed respectively to NAND gates 1, 2. Since the outputs from the inverters 3, 4 are fixed at L when the control signal is L, boosting operation of TrNn-1, Nn is not carried out and a voltage lower than the output voltage to be produced when the control signal is H by the threshold voltage of TrNn-1, Nn is outputted thus providing a plurality of boosted voltages.
