Abstract
A positive charge pumping circuit which is capable of reducing a sheet resistance and a threshold potential drop. The pumping circuit includes a pumping node, a power supply node, a first diode and at least one pumping stage, The pumping node provides a pumping potential. The supply node provides a power supply potential. An anode of the diode is coupled to the power supply node. The pumping stages are coupled in series between the pumping node and a cathode of the first diode. Each of the pumping stages includes a driving node and a control node, a pumping driving circuit, a transfer control circuit, a charge pumping circuit, and a potential control circuit.
