Abstract:
A power circuit to which an input power source is applied, the input power source supplying a first input potential on a high-potential side and a second input potential on a low-potential side, said power circuit supplying first to Nth potentials (where N.gtoreq.4), said power circuit comprising:a first output line that supplies said first input potential on a high-potential side as a Gth potential within said first to Nth potentials (where 1<G<N);a second output line that supplies said second input potential on a low-potential side as a Jth potential within said first to Nth potentials (where 1<J<N);a charge pump circuit which operates based on a given clock signal to thereby supply said first potential on the high-potential side, either directly or via an adjustment circuit; anda charge pump circuit which operates based on a given clock signal to thereby supply said Nth potential on the low-potential side, either directly or via an adjustment circuit.
