摘要： PROBLEM TO BE SOLVED: To solve the problem that a required base current cannot be sufficiently obtained from a control terminal because a current amplification rate h FE of each of HBTs (heterojunction bipolar transistor) is limited in a structure of a switch circuit device in which a base of each of the HBTs is directly connected to a control terminal while a base current required for driving of the HBTs must be supplied from the control terminal in this switch circuit device. SOLUTION: A driving FET in which the base of each of the HBTs forming a switching element is connected to its source is provided, a drain of the driving FET is connected to a power source terminal, and a gate thereof is connected to the control terminal. The driving FET conducts based on a control signal, and the HBTs operate based on a current to be supplied from the power source terminal. Thus, a control signal from a general control LSI can be utilized. Also, each unit FET of the driving FET is caused to respond to each unit HBT of the HBTs, thereby preventing breakage due to secondary breakdown of the HBTs. COPYRIGHT: (C)2007,JPO&INPIT

摘要：本発明に係るスイッチマトリックス回路（１００）は、複数個のスイッチ（Ｓ１'〜Ｓ１６'）が行及びカラムの構成にて編成され、電流検出回路は前記複数のスイッチ（Ｓ１'〜Ｓ１６'）と連結されている。また、前記電流検出回路は、前記複数のスイッチのカラム毎にトランジスタ（Ｑ１〜Ｑ４）及び少なくとも１つの抵抗（Ｒ１７〜Ｒ２０）を含んでいる。そして、カラム内の前記トランジスタによって増幅され、前記少なくとも１つの抵抗によって変換された電流は、選択された行に対する当該カラム内のスイッチ状態を示すロジックレベルとして検出される。また、電流検出処理では、一実施形態においては、スイッチマトリックスを走査するのに必要となるＩ／Ｏ線の数を最小限にする双方向の信号制御を採用することができ、また、別の実施形態においては、双方向信号走査によって、閉鎖スイッチを決定するための電圧レベルの検出を行える。

摘要： PROBLEM TO BE SOLVED: To switch a first clock signal being output to a second clock signal arbitrarily selected from a plurality of clock signals having different frequencies and phases while preventing the occurrence of a hazard. SOLUTION: A clock signal clk_i (i=1, 2,..., x), a selection signal of the clock signal sel_i, and a permission signal chen are respectively input. A plurality of unit circuits 10 -1 , 10 -2 ,...10 -x controls the supply or the suspension of the clock signal corresponding to the selection signal and the permission signal. A feedback circuit 30 monitors the output states of the plurality of unit circuits, and when each of the unit circuits stops outputting the clock signal as the first clock signal stops, supplies the unit circuits with the permission signal chen for permitting the supply of the second clock signal.

摘要： PROBLEM TO BE SOLVED: To provide an input and output circuit for using one terminal as an input and an output by switching in a simple constitution.
SOLUTION: An output-system signal processing circuit 1 is connected to an input/output common terminal 5 through a transistor 2, a capacitor 3, and an impedance matching resistor 4. An input-system signal processing circuit 10 is connected to the input/output common terminal 5 through a capacitor 8 and a transistor 9. One end of a transistor 6 as a switching means for open and close by an input/output switching signal is connected across the transistor 2 and the capacitor 3, while the other end of the transistor 6 is grounded. In this constitution, by switching the open and close of the transistor 6, the input/output common terminal 5 can be used as an input terminal and an output terminal.
