Patent ID: 8686787

Claim:
A circuital arrangement adapted to provide an output voltage to a load circuit, comprising: a plurality of inverter stages ring connected; and a plurality of voltage boosting stages serially connected, each voltage boosting stage being coupled with a corresponding inverter stage, wherein each voltage boosting stage comprises: at least one pump block, wherein an output voltage of a particular pump block in the at least one pump block is larger in magnitude than an input voltage to the particular pump block in the at least one pump block, and a driving circuit connected with an output of a corresponding inverter stage on one end and the at least one pump block on another end, wherein the driving circuit generates a first voltage and a second voltage based on the input voltage to the corresponding inverter stage, and wherein each of the first and second voltages are adapted to be applied to the at least one pump block, wherein: an output of a particular voltage boosting stage in the plurality of voltage boosting stages is higher in magnitude than an output of a previous voltage boosting stage in the plurality of voltage boosting stages, the output of the previous voltage boosting stage is an input to the particular voltage boosting stage, and a last voltage boosting stage in the plurality of voltage boosting stages is adapted to provide the output voltage to the load circuit.
