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)
Salivary biomarkers have been increasingly popular in stress research as saliva is easily produced and collection is non-invasive and not limited by geographical distance or lack of infrastructure. Several salivary biomarkers have been utilized in stress research, for instance, salivary cortisol, salivary amylase and salivary immunoglobulin A. Despite being(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)
An ultra-low power analog front end is presented to capture ExG (including ECG, EEG and EMG) signals. It consists of a capacitively coupled chopper instrument amplifier, a chopping spike filter and a VGA. Implemented in standard 0.35&#x03BC;m CMOS technology, this analog front end occupying 0.54 mm<sup>2</sup> chip area, while consuming only 3.96&#x03BC;A(More)
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)
