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)
A four-channel Application Specific Integrated Circuit (ASIC) is proposed to read out Charge Coupled Device (CCD) used for X-ray detection. Each channel, which consists of two incremental sigma delta (ΣΔ) Analog-to-Digital Converters (ADCs), can process the input signals in parallel. To reduce the mismatch between different channels, a digital calibration(More)
This paper presents a ΣΔ 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 ΣΔ DAC manufactured in SMIC 0.13-μm CMOS process occupies a(More)
A 14-bit 100MS/s self-calibrated Digital-to-Analog converter (DAC) is presented. Analog background self-calibration technique with a randomized calibration-period is adopted to improve the dynamic performance. The DAC is fabricated in SMIC 0.13-&#x00B5;m CMOS process and occupies a 1.29mm<sup>2</sup> die area. The measured DNL/INL is better than(More)
In recent years, natural disasters and environmental pollution events occur frequently and seriously threaten people's lives and property. The first step of disaster prevention and mitigation is obtaining the monitoring data of disaster situation. Currently, there are two main problems in transferring monitoring data, one is that disaster monitoring sensors(More)
A large-scale Reconfigurable Analog Processor (RAP), based on Field Programmable Analog Array (FPAA), and assisted by Configurable Digital Block (CDB), is introduced. Fine-grained Configurable Analog Blocks (CABs) are used in the FPAA structure for flexibility. Almost all analog functions can be realized through RAP and the digital parts further enhanced(More)
