    摘要: An object is to provide an antenna switch semiconductor integrated circuit which reduces a consumption current. To this end, of two control input signals which are fed to a logic circuit which controls turning on and off of a plurality of switching FETs, a control input signal for switching between a sending mode and a receiving mode is fed to an oscillation circuit, thereby making the oscillation circuit operate only during the sending mode under which the logic circuit needs a high voltage. A voltage raising circuit accordingly operates, whereby a raised voltage is supplied to the logic circuit. During the receiving mode, the oscillation circuit stops, and the voltage raising circuit stops. With a switch turned on using the logic circuit, a power source voltage is supplied directly to the logic circuit when the voltage raising circuit is not in operation. This shortens the operation time of the voltage raising circuit and reduces the consumption current.

    摘要: An output voltage Vout from a boost processing section 20 is divided by resistances 41 and 42, and a resultant divided output voltage Va is input to one of two input terminals of a comparator 45. A reference voltage Vb obtained by dividing a voltage Vcc by resistances 43 and 44 is input to the other input terminal of the comparator 45. The comparator 45 compares the divided output voltage Va with the reference voltage Vb, and when the divided output voltage Va is lower, outputs a HIGH voltage, and when the divided output voltage Va is higher, outputs a LOW voltage. Thereby, an signal oscillating section 10 performs oscillation at a radio frequency (an N-type CMOS FET 18 is in the OFF state) when the output voltage Vout does not exceed a threshold value determined by the reference voltage Vb, and performs oscillation at a low frequency (the N-type CMOS FET 18 is in the ON state) when the output voltage Vout exceeds the threshold value.

    摘要: The invention is directed to the provision of a two-input, four-output high frequency switch circuit that can prevent the occurrence of in-band ripples of insertion loss in an ON path. The high frequency switch circuit is constructed from six field effect transistors, and a signal is passed through a selected one of signal paths in the two-input, four-output high frequency signal switch having a total of six signal terminals, wherein four additional field effect transistors, each of which, when ON, provides a characteristic impedance matched to the characteristic impedance of an external circuit, are respectively connected between ground and the signal paths leading to the remaining four signal terminals to which the signal is not passed and which therefore become open ends. When the signal is not passed, the respective four field effect transistors are put in operation, thereby eliminating the effects of standing waves occurring on the respective paths leading to the four signal terminals acting as open ends.

    摘要: One end of each of five resistors is connected to each of the two ends and the respective intermediate points of a cascade of four depression-type FETs, while the other ends of the five resistors are provided with a predetermined voltage. This configuration fixes the source-drain potential of the four FETs. This fixing of the source-drain potential of the FETs permits stable application of a bias voltage for turning ON the FETs between the gate and the source each FET, so as to ensure the ON-OFF switching of the FETs.

    摘要: An antifuse comprised of an NMOS transistor or an NMOS capacitor includes a first terminal coupled to a gate electrode, a second terminal coupled to a diffusion layer, and a gate insulating film interposed between the gate electrode and the diffusion layer. A programming circuit includes a first programming circuit which has first current drive capability and which performs first programming operation and a second programming circuit which has second current drive capability larger than the first current drive capability and which performs second programming operation to follow the first programming operation. In the first programming operation, the first programming circuit breaks down the gate insulating film by applying a first programming voltage between the first terminal and the second terminal. In the second programming operation, the second programming circuit applies a second programming voltage lower than the first programming voltage between the first terminal and the second terminal.
