본 고안은 입력단자에 고전위가 인가되면 출력단자에 일정 주기를 가지는 펄스신호가 출력되는 단안정멀티바이브레이터에 있어서, 단안정멀티바이브레이터에 동작 전원을 공급하지 않고, 입력단자에 입력되는 고전위로 동작시킬 수 있게 한 바이어스(bias) 전압이 필요없는 단안정멀티바이브레이터에 관한 것이다.The present invention is a monostable multivibrator that outputs a pulse signal having a certain period to the output terminal when a high potential is applied to the input terminal, and operates at a high potential input to the input terminal without supplying operating power to the monostable multivibrator. It relates to a monostable multivibrator that does not require a bias voltage.
종래의 단안정멀티바이브레이터는 동작 전원이 항상 인가되어야 동작되게 구성되어 있으므로 전력의 소모가 많음은 물론 많은 소자가 필요하여 생산원가가 비싼 결함이 있었다.Since the conventional monostable multivibrator is configured to operate only when the operating power is always applied, it consumes a lot of power and has many defects, requiring a large number of devices.
본 고안은 종래의 이와 같은 결함을 감안하여 별도의 동작 전원이 필요없이 입력단자에 인가되는 고전위로 단안정멀티바이브레이터 동작되게 안출한 것으로 이하 첨부된 도면에 의하여 본 고안을 보다 상세히 설명하면 다음과 같다.The present invention is designed to allow the monostable multivibrator to operate at a high potential applied to an input terminal without a separate operation power source in view of the above-described defects. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. .
제1도에 도시한 바와 같이 입력단자(A)에 접속되는 저항(R1)을 트랜지스터(TR1)의 에미터에 접속하여 그의 콜렉터는 다이오드(D1)의 캐소드 및 다이오드(D2)의 애노드, 트랜지스터(TR2)의 베이스, 콘덴서(C1), 가변저항(VR1)에 공통접속하고, 베이스는 다이오드(D1)의 애노드 및 트랜지스터(TR2)의 콜렉터, 저항(R2), 출력단자(B)에 공통 접속하여 구성한 것이다.As shown in FIG. 1, the resistor R 1 connected to the input terminal A is connected to the emitter of the transistor TR 1 so that its collector is connected to the cathode of the diode D 1 and the diode D 2 . Commonly connected to the anode, the base of the transistor TR 2 , the capacitor C 1 , the variable resistor VR 1 , and the base is the anode of the diode D 1 and the collector of the transistor TR 2 , the resistor R 2 . The output terminal B is connected in common.
이와 같이 구성되는 본 고안의 작용효과를 상세히 설명하면 다음과 같다.If described in detail the effect of the present invention is configured as follows.
제2도의 (a)에 도시한 바와 같이 시간(to)에 입력단자(A)로 고원위가 입력되면, 트랜지스터(TR1)의 애미터에 고전위가 인가되어 온되므로 그의 콜렉터에는 고전위가 출력되어 제2도의 (b)에 도시한 바와 같이 콘덴서(C1)에 충전되기 시작하고, 또한 트랜지스터(TR1)의 베이스 전위도 고전위가 되어 출력단자(B)에는 시간(to)에 고전위가 출력된다.As shown in (a) of FIG. 2, when the plateau phase is input to the input terminal A at the time t o , the high potential is applied to the emitter of the transistor TR 1 , so that the collector has a high potential. Is outputted and begins to charge in the capacitor C 1 as shown in FIG. 2 (b), and the base potential of the transistor TR 1 also becomes high potential, and the time t o at the output terminal B is Outputs a high potential.
이와 같이 시간(to)에 입력단자(A)에 고전위가 입력되어 콘덴서(C1)에 충전되기 시작하고, 출력단자(B)에는 고전위가 출력되는 상태에서 일정 시간(t1)이 경과하여 콘덴서(C1)에 충전되는 전압이 트랜지스터(TR2) 및 다이오(D2)를 온시키기 충분한 전압, 즉 제2도의 (c)에 도시한 바와 같이 콘덴서(C1)에 충전된 전압이 트랜지스터(TR2) 및 다이오드(D2)의 충분한 바이어스 전압이 되면 트랜지스터(TR2) 및 다이오드(D2)가 온되어 전류미러로 동작되므로 트랜지스터(TR2)는 온된 상태를 유지하게 되고, 다이오드(D1)는 오프된다. 따라서 이때 출력단자(B)에는 제2도의 (b)에 도시한 바와 같이 시간(t1) 이후에 저전위가 출력된다.As described above, the high potential is input to the input terminal A at the time t o and begins to be charged in the capacitor C 1 , and the constant time t 1 is applied to the output terminal B while the high potential is output. The voltage that is subsequently charged in the capacitor C 1 is sufficient to turn on the transistors TR 2 and the diode D 2 , that is, the voltage charged in the capacitor C 1 as shown in FIG. 2C. a transistor (TR 2) and a diode when a sufficient bias voltage (D 2) transistor (TR 2) and a diode (D 2) is so turned on and operating, a current mirror transistor (TR 2) is to keep the ondoen state, Diode D 1 is off. Therefore, at this time, the low potential is output to the output terminal B after the time t 1 as shown in (b) of FIG.
여기서, 출력단자(B)로 출력되는 펄스신호의 폭(T1)은 가변저항(VR1)의 값을 임의로 가변하여 조절할 수 있다.Here, the width T 1 of the pulse signal output to the output terminal B may be adjusted by arbitrarily varying the value of the variable resistor VR 1 .
이상에서 설명한 바와 같이 별도의 동작 전원을 공급하지 않고서도 하나의 펄스신호가 출력되는 단안정멀티바이브레이터로 동작되므로 필요없는 전력의 소모를 줄일 수 있음은 물론 사용되는 소자의 수가 적어 집적회로화 할 경우에는 칩(chip)의 면적을 줄일 수 있는 효과가 있다.As described above, since it operates as a monostable multivibrator that outputs one pulse signal without supplying a separate operating power source, it is possible to reduce unnecessary power consumption and to integrate an integrated circuit with fewer devices. There is an effect that can reduce the area of the chip (chip).
