  • 본 논문에서는 고속 혼성모드 집적회로를 위한 온-칩(on-chip) CMOS 전류 및 전압 레퍼런스 회로를 제안한다. 제안하는 전류 레퍼런스 회로는 기존의 전류 레퍼런스 회로에서 부정확한 전류 값을 조정하기 위해 주로 사용되는 아날로그 보정 기법과는 달리 디지털 영역에서의 보정 기법을 사용한다. 또한, 제안하는 전압 레퍼런스 회로는 고속으로 동작하는 혼성모드 집적회로의 출력단에서 발생할 수 있는 고주파수의 잡음 성분을 최소한으로 줄이기 위해 고주파 신호 성분에 대해 작은 출력 저항을 볼 수 있는 구조의 레퍼런스 전압 구동회로를 사용한다. 이 레퍼런스 전압 구동회로는 전력 소모 및 칩 면적을 최소화하기 위해서 저 전력의 증폭기와 크기가 작은 온-칩 캐패시터를 사용하여 구현하였다. 제안하는 레퍼런스 회로는 0.18 um n-well CMOS 공정으로 설계 및 제작되었으며, 250 um x 200 um의 면적을 차지한다. 칩 제작 및 측정결과, 제안하는 전류 및 전압 레퍼런스 회로는 공급 전압 및 온도의 변화에 대해서 각각 2.59 %/V와 48 ppm/℃의 변화율을 보인다.

  • To understand the recent characteristics of the papers published in the Journal of Korean Academy of Conservative Dentistry(JKACD), All the papers in the JKACD of 1992 to 2001 were analyzed. A total of 513 papers were classified according to its type, fold and subject of the study, school and the number of authors, references, and written language. The results were as follows ; 1 According to the type of the paper, 506(98.6%) were original articles, 3(0.6%) were review articles, and 4(0.8%) were case reports. 2. Anual proportion of papers in the fold of operative dentistry was similar to that of endodontics 3. In the field of operative dentistry, esthetic restorative materials and bonding to tooth constituted major subjects of the studies. In the field of endodotics, pulp biology was prominent and canal shaping, endodontic microbiology and canal obturation were steadily reported. 4. According to author's school, similar number of papers were published in the field of operative den tistry and endodontics in general. However, some schools showed preponderances. 5. Most studies were done by two or more authors. Studies published by two authors were most 6. Fifty(9.7%) papers were done in collaboration with workers of the other field. 7. Average number of references cited in the papers was 41.2, including domestic references of 1.8. 40.7% of the papers was shown to cite no domestic papers at all. 8. Twenty-eight(5.5%) papers were written in English, with increasing ratio.
