본 발명은 디지탈/아날로그 변환기 및 아날로그/디지탈 변환기 등에 사용되는 사다리형 저항(lodder-type resistor)에 관한 것으로, 특히 사다리형 저항과 금속재잴의 패드(pad)를 접속시키는 사다리형 저항의 접속장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to ladder-type resistors used in digital / analog converters and analog / digital converters. It is about.

일반적으로 사다리형 저항은 제 1 도 및 제 2 도에 도시한 바와같이 확산(diffused)저항으로 다수개의 저항(R1∼Rn)이 직렬로 연결된 구조로 되어 있고, 그 사다리형 저항(1)의 각 저항(R1∼Rn)의 접속점에는 디지탈/아날로그 변환기의 출력단자 및 아날로그/디지탈 변환기의 입력단자등이 접속되는 탬(T1∼Tn-1)이 형성되어 있으며, 그 사다리형 저항(1)이 종단부에는 패드(2)(2')가 접속되어, 그 패드(2)(2')를 통해 사다리형 저항(1)에 기준전압(V+)(V-)이 공급되게 되어 있다. 도면의 설명중 미설명부호 3은 접속부를 나타낸다.In general, the ladder resistor has a structure in which a plurality of resistors R 1 to R n are connected in series by a diffused resistor as shown in FIGS. 1 and 2, and the ladder resistor 1 At each connection point of the resistors R 1 to R n , a tab T 1 to T n-1 is formed to which an output terminal of a digital / analog converter and an input terminal of an analog / digital converter are connected. Pads 2 and 2 'are connected to the ends of the resistor 1, and the reference voltages V + and V - are supplied to the ladder resistor 1 through the pads 2 and 2'. It is supposed to be. In the description of the drawings, reference numeral 3 denotes a connection portion.

이와같은 사다리형 저항(1)에 있어서, 종래에는 패드(2)(2')와 사다리형 저항(1)을 접속한 경우에 사다리형 저항(1)의 종단부에 패드(2)(2')의 종단부를 겹친 후 패드(2)(2')와 사다리형 저항(1)를 접속하였다.In such a ladder resistor 1, conventionally, when pads 2, 2 'and a ladder resistor 1 are connected, pads 2 and 2' are terminated at the end of the ladder resistor 1; ), The pads (2) (2 ') and the ladder resistor (1) were connected.

그러나, 이와같이 패드(2)와 사다리형 저항(1)을 접속시키면, 집적소자의 제조중에 마이크(mask)의 비정렬(misalignment)로 인하여 접속부(3)(3')와 탭(T1)(Tn-1)간의 간격(d1)(d2)의 변하게 되며, 저항(R1)의 변화에 따라 아날로그/디지탈 변환기 및 디지탈/아날로그 변환기가 제로 오프세트 에러(zero offset error)를 발생함은 물론 저항(Rn)의 변환에 따라 풀 오프세트 에러(full offset error)를 발생하게 되는 결함이 있었다.However, when the pad 2 and the ladder resistor 1 are connected in this way, the connection part 3 (3 ') and the tab T 1 (i.e., due to misalignment of the mask during the manufacture of the integrated device) The interval d 1 and d 2 between T n-1 ) changes, and the analog / digital converter and the digital / analog converter generate a zero offset error according to the change of the resistance R 1 . Of course, there is a defect that causes a full offset error according to the conversion of the resistor R n .

본 발명은 이와같이 종래의 결함을 감안하여, 패드와 사다리형 저항간의 접속저항이 매우 작게함은 물론 마이크의 비정렬을 보상하는 사다리형 저항의 접속장치를 창안한 것으로, 이를 첨부된 제 3 도 및 제 4 도의 도면에 의하여 상세히 설명하면 다음과 같다. 제 3 도는 본 발명의 사다리형 저항 접속장치 구성도로서, 이에 도시한 바와 같이 사다리형 저항(11)의 양종단부에 수평부(12') 및 수직부(12")를 가지는 H자형 접속판(12)을 형성하고, 패드(13)의 종단부에는 상기 접속판(12)보다 넓은 접속판(14)을 형성하여 접속판(12)의 상부에 접속판(14)을 덮은 후 접속판(12)의 수직부(12")와 접속판(14)의 양측을 접속하여 구성한다.The present invention in view of the conventional defects as described above, the connection resistance between the pad and the ladder-type resistor is very small, as well as to create a connection device of the ladder-type resistor that compensates for the misalignment of the microphone. The detailed description with reference to FIG. 4 is as follows. 3 is a block diagram of a ladder resistor connection device according to the present invention. As shown therein, an H-shaped connecting plate having horizontal portions 12 'and vertical portions 12 " 12 is formed, and at the terminal of the pad 13, a connection plate 14 wider than the connection plate 12 is formed to cover the connection plate 14 on the connection plate 12, and then the connection plate 12. The vertical portion 12 " and both sides of the connecting plate 14 are connected.

제 3 도의 설명중 미설명 부호 15는 수직부(12")와 접속판(14)간의 접속부를 표시한 것이다.In the description of FIG. 3, reference numeral 15 denotes a connecting portion between the vertical portion 12 ″ and the connecting plate 14.

이와같이 구성된 제 3 도를 등가회로도로 나타내면 제 4 도와 같다.The third diagram configured in this manner is equivalent to the fourth diagram in an equivalent circuit diagram.

제 4 도에서 저항(R11)은 사다리형 저항(11의 전체 저항이고, 저항(r12)은 접속부(15)에서 집적소자의 외부핀까지의 저항이며, 저항(R13)은 접속부(15) 및 접속부(15)에서 사다리형 저항(11)의 주저항까지의 유효저항이며, 저항(R14)은 비정렬에 의한 저항의 변화값이다.In FIG. 4, the resistor R 11 is the total resistance of the ladder resistor 11, the resistor r 12 is the resistor from the connection portion 15 to the external pin of the integrated element, and the resistor R 13 is the connection portion 15. ) And the connecting portion 15 are effective resistances from the main resistance of the ladder type resistor 11, and the resistor R 14 is a change value of the resistance due to misalignment.

이와같은 본 발명은 수직부(12")와 접속판(14)의 접속부(15)가 병렬로 형성되고, 접속부(15)의 길이(d11)가 사다리형 저항(11)의 폭(d12)보다 커 유효접촉면적이 증가하므로 낮은 접속저항을 갖게되고, 또한 마이크의 비정렬로 인하여 접속부(15)가 좌우로 이동되면, 일측의 접속부(15)의 저항이 증가하는 반면에 반대측의 접속부(15)의 저항은 감소 즉, 두개의 접속부(15)는 균형을 유지하는 구조로 병렬접속되므로 접속부(15)의 저항의 변화는 서로 보정하게 된다.In the present invention, the vertical portion 12 " and the connecting portion 15 of the connecting plate 14 are formed in parallel, and the length d 11 of the connecting portion 15 is the width d 12 of the ladder resistor 11. Since the effective contact area is larger than), the contact area has a low connection resistance, and when the connection part 15 is moved left and right due to misalignment of the microphone, the resistance of the connection part 15 on one side increases, while The resistance of 15 is reduced, i.e., since the two connections 15 are connected in parallel in a balanced structure, the change in resistance of the connections 15 is corrected with each other.

제 4 도의 등가회로도에서 전체 저항의 값은 하기의 식과 같이되고,In the equivalent circuit diagram of FIG. 4, the value of the total resistance is represented by

로 되고, 상기 종래의 접속장치에서는 저항의 변화가

In the conventional connection apparatus, the change in resistance

Therefore, the error of the resistance value is very small compared with the conventional one.

그리고, 접속부(15)의 길이(d11)가 수평부(12')의 폭(d13)보다 크므로 사다리형 저항(11)에 대한 유효접촉 면적이 마스크의 비정렬때 영향을 받지 않게 된다.In addition, since the length d 11 of the connection part 15 is larger than the width d 13 of the horizontal part 12 ′, the effective contact area with respect to the ladder resistor 11 is not affected when the mask is misaligned. .

이상에서 상세히 설명한 바와같이 본 발명은 접속부의 접촉 저항을 낮게 함은 물론 마스크의 비정렬로 인한 저항값의 변화를 보상하므로 제로 오프세트 에러 및 풀 오프세트 에러가 없는 아날로그/디지탈 변환기 및 디지탈/아날로그 변환기를 제조할 수 있는 효과가 있다.As described in detail above, the present invention not only lowers the contact resistance of the connection but also compensates for the change in the resistance value due to the misalignment of the mask, thereby eliminating zero offset error and full offset error, and digital / analog There is an effect to manufacture a transducer.
