본 논문에서는 rail-to-rail 복합입력단을 갖는 증폭회로의 옵셋전압을 보상해주기 위한 방법을 제안하고 집적회로로 구현하였다. 두 개의 보조증폭회로와 옵셋보상 커패시터들을 사용하여 NMOS 차동쌍과 PMOS 차동쌍의 옵셋을 각각 보상하고, ping-pong control을 사용하여 연속시간 동작이 가능한 3V rail-to-rail CMOS 증폭회로를 설계하였다. 설계된 증폭회로를 0.8㎛ single-poly double metal CMOS 공정으로 제작한 후 성능을 측정한 결과, 옵셋보상후의 옵셋전압은 옵셋보상전에 비해 약 20배정도 감소하였다.

Background : The one-leg standing (OLS) test is a method of evaluating trunk stability. The transverse abdominis (TrA) is an important muscle that contributes to trunk stability during functional movement through abdominal draw-in maneuver (ADIM). The gluteus medius (Gmed) is also important for functional movement and for stability of the hip joints in the muscles that prevent lateral deviation of the trunk in OLS. During ADIM, the Gmed, TrA and internal oblique (IO) muscles are activated. It...

Objective: The aim of this study was to objectively evaluate sensory disturbance in cervical spondylosis using grip force and investigate the relationship between the grip force and upper extremity function. Design: Cross-sectional study. Methods: Eleven cervical spondylosis patients with paresthesia conducted grip and lift tasks using a precision grip with the tips of the thumb and index finger on either side. The sum of the grip force used during the first four seconds was calculated and...

the experimental group post intervention (p<0.05), and there was a significant improvement in the experimental group compared with the control group (p<0.05). The 30CST and NPRS scores improved significantly in the experimental group compared to the control group (p<0.05), and there was a significant difference between the two groups (p<0.05). Weight distribution was significantly improved in the experimental group compared with the control group, (p<0.05), but there was no significant differenc...

after 3 weeks administration of vitamin D in the subjects with diabetes and in the control subjects (p<0.05). The response to occlusion was not significantly different within each group before and after vitamin D administration, but the group with diabetes had a significantly lower blood flow response to occlusion than did the controls (p<0.05). Conclusions: Acute doses of vitamin D may impair nitric oxide production and reduce blood flow to tissue during stressors in people with diabetes.

in the underlying tissues. Design: Case control study. Methods: First, microcurrent was measured as decreased blood flow induced hypoxia in healthy subjects. Next, reliability was assessed by measuring over ten days with set variations in pressure and distance between the electrodes. Finally, measurements over sprained ankle were compared to measurements over comparable uninjured areas on the same injured subject. Results: For the blood flow test phase, microcurrent significantly decreased an...

Objective: Coenzyme (CoQ10) is an enzymatic co factor used in normal cellular metabolism. Recent evidence shows that in people with heart disease it can reverse endothelial cell damage in the blood vessels. It is also a potent antioxidant. Design: One group pretest-posttest design. Methods: In the present study, endothelial function was evaluated using the response to occlusion and heat before and 2 weeks after administration of CoQ10, 300 mg/day. Thirty Eight subjects, who are physical therapy...
