International ClassG06K 19/05AbstractThe invention provides a circuit which provides a stabilized boosting in the case where a semiconductor device typified by a non-contact ID chip includes a circuit which requires a higher voltage than a logic circuit does. By inputting an alternating signal inputted from an antenna to a charge pump circuit as it is or through a logic circuit, a charge pump can operate with a stabilized frequency that a clock frequency is not affected by a variation of elements and the ambient temperature, thus a stabilized boosting can be provided.Other References
