Thus, biotin-modified exendin-3 or exendin-4 derivatives are useful for treating diseases, which can be caused by the excessive secretion of insulin, the lowering of plasma glucose, the inhibition of gastric or intestinal motility, the inhibition of gastric or intestinal emptying or the inhibition of food intake. Particularly, the biotin-modified exendin-3 or exendin-4 derivatives are useful for the treatment of diabetes, obesity and irritable bowel syndromes. | 10-20-2011 |

| 20090261998 | APPARATUS AND METHOD FOR SIGMA-DELTA ANALOG TO DIGITAL CONVERSION - A method and apparatus are provided for sigma-delta (ΣΔ) analog to digital conversion, the method including receiving an analog signal, sampling the received signal, comparing the sampled signal with a constant reference voltage, providing at least one high-order bit responsive to the constant reference comparison, comparing the sampled signal with a variable reference voltage, providing at least one low-order bit responsive to the variable reference comparison, and combining the at least one high-order bit with the at least one low-order bit; and the apparatus including a comparator, a first ADC portion supplying the comparator with a constant reference voltage for providing at least one high-order bit, and a second ADC portion supplying the comparator with a variable reference voltage for providing at least One low-order bit. | 10-22-2009 |
| 20090289823 | Sigma-delta analog-to-digital converter and solid-state image pickup device - A sigma-delta analog-to-digital converter may include a sigma-delta modulator and a decimation filter. The sigma-delta modulator may convert a first analog input signal into a first bit stream having a first pattern using sigma-delta modulation and convert a second analog input signal into a second bit stream having a second pattern using the sigma-delta modulation. The decimation filter may integrate the number of bits having a particular value in the first bit stream, output a first digital value, calculate a bitwise complement value of the first digital value, integrate the number of bits having the particular value in the second bit stream with the bitwise complement value of the first digital value as an initial value of a second digital value, and output the second digital value. | 11-26-2009 |
| 20090295956 | Decimation filters, analog-to-digital converters including the same, and image sensors including the converters - An image sensor includes an analog-to-digital converter (ADC) and a decimation filter. The decimation filter includes a first digital data generator and a second digital data generator. The first digital data generator is configured to integrate sigma-delta modulated M-bit pixel data and output N-bit pixel data based on an integration result. The second digital data generator is configured to integrate the N-bit pixel data, generate P-bit pixel data based on an integration result, and output the P-bit pixel data as decimated data. | 12-03-2009 |
