    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: A first phase comparator 22 of digital type and a second phase comparator 32 of sampling type are provided. Near a lock phase, an output current Iout2 is fed from the second phase comparator 32 to a voltage-controlled oscillator 14 through a change-over switch 40. In other phases, an output current Iout1 is fed thereto from the first phase comparator 22. When a reference signal fs is missing, a complementing circuit 50 complements a pulse to at least the reference signal fs input to the first phase comparator 22. A noise detecting/removing circuit 60 detects and removes noise from the reference signals fs, permits the reference signals fs to be fed to the first and second phase comparators 22 and 23, and halts the operations of the two phase comparators 22 and 32 for only a predetermined period of time after the noise has been detected. Therefore, the PLL circuit stably operates and characters are clearly displayed on a screen even when the noise is contained in the horizontal synchronizing signals of the video signals or even when the signals are missing.

    摘要: The detector is reduced in DC power consumption when an input signal is at a low amplitude level. The detector includes first and second input terminals, first and second transistors, and a load element. The first and second input terminals are supplied with complementary input signals reverse to each other in phase. The first input terminal is connected to the first input electrode of the first transistor and the second input electrode of the second transistor. The second input terminal is connected to the second input electrode of the first transistor and the first input electrode of the second transistor. The load element is connected between output electrodes of the transistors and an operating voltage point. A detection voltage resulting from full-wave rectification arises from a circuit node. In the condition where a signal input to the input terminals is at a low amplitude level, the transistors are both in OFF state. Thus, DC power consumption is reduced.
