Abstract
트랜지스터의 스위칭동작시 발생되는 전류노이즈를 제거하는 정류회로가 개시되고 있다. 본 발명은 소정레벨의 전압원과 접속되어 소망하는 레벨의 제 1교류신호 및 상기 제 1교류신호와 위상이 상반되는 제 2교류신호로 변환하는 제 1 및 제 2단자로 각각 출력하는 전압변환수단과, 소망하는 레벨의 출력신호를 나타내는 출력단자와, 제 2단자에 접속되는 스위칭 제어단자를 구비하고, 제 1단자와 상기 출력단자사이에 접속되며, 제 2교류신호에 대응하여 제 1단자와 출력단자를 스위칭 접속하여 전압변화수단으로부터 출력되는 교류신호들을 제 3단자로 출력하는 제 1스위칭수단과, 제 1단자에 접속되는 스위칭 제어단자를 구비하고, 제 2단자와 상기 출력단자 사이에 접속되며, 제 1교류신호에 대응하여 제 2단자와 출력단자를 스위칭 접속하여 전압변환수단으로부터 출력되는 교류신호들을 출력단자로 출력하는 제 2스위칭수단으로 구성되며 상기 제 1 및 제 2스위칭수단중 적어도 하나의 스위칭 수단이 노이즈 성분을 제거하는 스위칭 수단이다. 본 발명에 따르면 NOS FET의 스위칭 동작시 발생되는 스파이크 성분을 나타내는 전류 노이즈를 제거하며, 또한 전류 노이즈를 제거하여 회로의 전가기간섭(EMI : Electromagnetic interference)를 감소 시킬 수 있으며, 또한 전류노이즈를 제거하여 회로의 스위칭 손실을 감소 시킬수 있다.A rectifying circuit for eliminating current noise generated during a switching operation of a transistor is disclosed. The present invention provides voltage conversion means for outputting first and second terminals respectively connected to a voltage source having a predetermined level and converting into a first alternating signal having a desired level and a second alternating signal having a phase opposite to that of the first alternating signal; And an output terminal for indicating an output signal of a desired level, and a switching control terminal connected to the second terminal, and connected between the first terminal and the output terminal, the first terminal and the output corresponding to the second alternating signal. A first switching means for switching the terminals and outputting the AC signals output from the voltage change means to the third terminal, and a switching control terminal connected to the first terminal, and connected between the second terminal and the output terminal. And second switching means for switching the second terminal and the output terminal in response to the first alternating signal to output AC signals output from the voltage converting means to the output terminal. At least one switching means of the first and second switching means is a switching means for removing a noise component. According to the present invention, the current noise indicating the spike component generated during the switching operation of the NOS FET can be removed, and the current noise can be eliminated to reduce the electromagnetic interference (EMI) of the circuit, and also to remove the current noise. This can reduce the switching losses of the circuit.
