Claims (4)

제1기준신호 및 제2기준신호와 귀환된 출력전압(VD)을 받는 비교기 각각의 출력은 래치(L)에 인가되고, 이 래치의 출력은 버퍼를 거쳐 캐패시터에 의해 상기한 출력전압(VD)을 얻도록 하므로써, 주파수 변화폭이 증대되므로 한 VCO(Voltage Controlled Oscillator).The output of each of the comparators receiving the first reference signal and the second reference signal and the output voltage VD fed back is applied to the latch L, and the output of the latch is passed through the buffer to the output voltage VD by the capacitor. As a result, the frequency variation is increased so that a voltage controlled oscillator (VCO) can be obtained. 제1항에 있어서, 상기한 기준전압중 제1기준전압(Vrf1)은 제2기준전압(Vrf2)보다 높게 설정되는 것을 특징으로 하는 VCO.The VCO of claim 1, wherein the first reference voltage Vrf1 is set higher than the second reference voltage Vrf2. 제1항에 있어서, 상기한 버퍼는 다수의 직렬 연결된 인버터 내지는 레벨 쉬프터인 것을 특징으로 하는 VCO.The VCO of claim 1, wherein the buffer is a plurality of serially connected inverters or level shifters. 제1항에 있어서, 상기한 래치(L)는 R-S 프립플롭으로 구성되는 것을 특징으로 하는 VCO.VCO according to claim 1, characterized in that said latch (L) consists of an R-S preflop. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
