There is an urgent need for an efficient approach to obtain a large-scale and renewable source of functional human vascular smooth muscle cells (VSMCs) to establish robust, patient-specific tissue model systems for studying the pathogenesis of vascular disease, and for developing novel therapeutic interventions. Here, we have derived a large quantity of(More)
This paper presents an energy-efficient reconfigurable 3<sup>rd</sup>-order continuous-time &#931;&#916; modulator, which can satisfy multi-band modes for 4G-LTE application. To expand the reconfigurable bandwidth range and optimize the energy efficiency, this work employs a flexible architecture, which can switch between feed-forward and feed-back(More)
This paper presents a &#931;&#916; DAC with channel filtering for multi-standard wireless transmitters. It can be digitally programmed to satisfy specifications of WCDMA, TD-SCDMA and GSM standards. The measured SFDR are 62.8/60.1/75.5 dB for WCDMA/TD-SCDMA/GSM mode, respectively. The &#931;&#916; DAC manufactured in SMIC 0.13-&mu;m CMOS process occupies a(More)
