| 3 | A 10-bit 110 MHz SAR ADC with asynchronous trimming in 65-nm CMOS显示文摘A 10-bit 110 MHz SAR ADC with asynchronous trimming is presented.In this paper,a high linearity sampling switch is used to produce a constant parasitical barrier capacitance which would not change with the range of input signals.As a result,the linearity of the SAR ADC will increase with high linearity sampled signals.Farther more,a high-speed and low-power dynamic comparator is proposed which would reduce the comparison time and save power consumption at the same time compared to existing technology.Additionally,the proposed comparator provides a better performance with the decreasing of power supply.Moreover,a highspeed successive approximation register is exhibited to speed up the conversion time and will reduce about 50%register delay.Lastly,an asynchronous trimming method is provided to make the capacitive-D AC settle up completely instead of using the redundant cycle which would prolong the whole conversion period.This SAR ADC is implemented in 65-nm CMOS technology the core occupies an active area of only 0.025 mm^2 and consumes 1.8 mW.The SAR ADC achieves SFDR > 68 dB and SNDR > 57 dB,resulting in the FOM of 28 f J/conversion-step.From the test results,the presented SAR ADC provides a better FOM compared to previous research and is suitable for a kind of ADC IP in the design SOC. | Daiguo Xu Shiliu Xu Xi Li Jie Pu | 2017 | Journal of Semiconductors2017，38，4： | 0 |
| 4 | Aligned 3D porous polyurethane scaffolds for biological anisotropic tissue regeneration显示文摘A green fabrication process(organic solvent-free)of artificial scaffolds is required in tissue engineering field.In this work,a series of aligned three-dimensional(3D)scaffolds are made from biodegradable waterborne polyurethane(PU)emulsion via directional freeze–drying method to ensure no organic byproducts.After optimizing the concentration of polymer in the emulsion and investigating different freezing temperatures,an aligned PUs scaffold(PU14)generated from 14wt%polymer content and processed at196C was selected based on the desired oriented porous structure(pore size of 32.569.3 lm,porosity of 92%)and balanced mechanical properties both in the horizontal direction(strength of 41.3 kPa,modulus of 72.3 kPa)and in the vertical direction(strength of 45.5 kPa,modulus of 139.3 kPa).The response of L929 cells and the regeneration of muscle tissue demonstrated that such pure material-based aligned 3D scaffold can facilitate the development of orientated cells and anisotropic tissue regeneration both in vitro and in vivo.Thus,these pure material-based scaffolds with ordered architecture have great potentials in tissue engineering for biological anisotropic tissue regeneration,such as muscle,nerve,spinal cord and so on. | Weiwei Lin Wanling Lan Yingke Wu Daiguo Zhao Yanchao Wang Xueling He Jiehua Li Zhen Li Feng Luo Hong Tan Qiang Fu | 2020 | Regenerative Biomaterials2020，7，1： | 0 |
