摘要： In an IC card, even when undershoot or overshoot which occurs upon an amplitude change by communication data is large, the change is accurately detected. A semiconductor device has antenna terminals, a power supply circuit for generating power supply voltage from an AC signal supplied to the antenna terminals, and a receiver circuit for demodulating an information signal superimposed on the AC signal. The receiver circuit includes a rectifier circuit, a filter circuit, a capacitor, an amplifier, a feedback path, a switch circuit, a binarizing circuit, and a control circuit. An output of the amplifier is transmitted to an inverting input terminal thereof, and the switch circuit is controlled by an output of the control circuit. In a predetermined period since level changes of an output of the binarizing circuit, the switch circuit is controlled to an off state by the output of the control circuit.

摘要： The semiconductor integrated circuit includes: a pair of antenna terminals; a rectifier; a source-voltage terminal; a shunt regulator; a series regulator. When the voltage of the inside source line rises to or above a first set voltage, the shunt regulator passes a pull-down current through a pull-down transistor. When the voltage of the inside source line drops to or below the second set voltage, the series regulator passes a pull-up current through a pull-up transistor. The first set voltage is set to be higher than the second set voltage in voltage level. With the semiconductor integrated circuit, the competition of actions of the two regulators is prevented. The semiconductor integrated circuit is arranged to work in contact and noncontact operation modes, and a stable source voltage can be supplied to an internal circuit thereof.

摘要： A semiconductor integrated circuit device (IC) and a contactless IC card including a receiver circuit that is able to stably demodulate information signals superimposed on AC signals from an interrogator. The receiver circuit included in the IC is equipped with antenna terminals, a power supply circuit, and a filter circuit. The information signal from which a high frequency component was eliminated through the filter circuit is input via a capacitor to an inverting input terminal of an operational amplifier and a reference voltage is input to a non-inverting input terminal thereof. After the information signal is fed back through a feedback path to the non-inverting input terminal of the operational amplifier, that signal is amplified and the amplified information signal is binarised by a binarising circuit, thereby data transmitted from the interrogator is demodulated. The contactless IC card comprises an antenna coil and the IC including this receiver circuit.

摘要： In an IC card in which an internal circuit is operated by an internal power supply formed from alternate current from outside received by an antenna, the voltage of the internal power supply sometimes changes due to the operation of the internal circuit. Therefore, the voltage controlling circuit of the present invention includes a voltage controlling current source, and when the internal circuit is not operated and the current higher than a predetermined current is detected in the voltage controlling current source, an operating current detector circuit outputs an enable signal. When the internal circuit is operated in response to the enable signal, the current consumed in the internal circuit is subtracted from the current passing through the voltage controlling current source. Consequently, the current change in the entire internal power supply can be prevented, and the output voltage of the internal power supply can be kept constant.

摘要： To augment the temperature dependence of the voltage used to detect temperature in a semiconductor integrated circuit device having a temperature detection function, the operating power supply voltage of the semiconductor integrated circuit device has needed to be enhanced. It becomes possible for such a semiconductor integrated circuit device to generate a voltage of great temperature dependence, even under a low operating power supply voltage, by including: a temperature-to-current converter which outputs a first electric current proportional to temperature; a current generator which outputs a second electric current having extremely small temperature dependence; a current subtracter which outputs a third electric current proportional to a differential current obtained by subtracting the second electric current from the first electric current; and a current-to-voltage converter which converts the third electric current into a voltage.
