—A high slew-rate amplifier with push–pull output driving capability is proposed to enable an ultra-low quiescent current (1 A) low-dropout (LDO) regulator with improved transient responses. The proposed amplifier eliminates the tradeoff between small and large slew-rate that is imposed by the tail-current in conventional amplifier design. Push–pull output(More)
—The design issues of a single-transistor-control (STC) low-drop-out (LDO) based on flipped voltage follower is discussed in this paper, in particular the feedback stability at different conditions of output capacitors, equivalent series resistances (ESRs) and load current. Based on the analysis, an STC LDO was implemented in a standard 0.35-m CMOS(More)
A system-on-chip passive UHF RFID tag with embedded temperature sensor is developed in a standard 0.18µm CMOS process for the EPC Gen-2 protocol from 860-960MHz [1]. Flip-chip technology is used to bond the developed tag IC to an antenna to realize a complete tag inlay, which is successfully demonstrated and evaluated in real-time wireless communications(More)
1  Abstract—The dual-band recording of the local-field potential (LFP, 0.1Hz~200Hz) and the spike potential (SP, 200Hz~10kHz) is important for physiological studies at the cellular level. Recent study shows that the LFP signal plays important roles in modulating many profound cellular mechanisms. Although various bio-signal acquisition circuits have been(More)
—This paper analyzes the geometry-dependent parasitic components in multifin double-gate fin field-effect transistors (FinFETs). Parasitic fringing capacitance and overlap capacitance are physically modeled as functions of gate geometry parameters using a conformal mapping method. Also, a physical gate resistance model is presented, combined with parasitic(More)
In this paper, a new Correlated Double Sampling (CDS) Technique based on Fixed Voltage Difference (FVD) is introduced. Compared with the traditional CDS technique with voltage sampling for A/D conversion, this method has the advantage of low voltage capability, which relieves the high resolution requirement of the subsequent A/D converter as a result of the(More)
This paper presents a framework to develop a generic and physical Double-Gate MOSFET model. Due to limited available physical data and existence of a large variety of device structures, flexibility to assemble model modules to accommodate different device structures takes a much high precedence compared with conventional modeling approaches. In addition,(More)
To determine whether changes in membrane potential affect the extent of mast cell degranulation, compound 48/80 was added to rat peritoneal mast cell suspensions in the absence or presence of potassium channel openers (KCOs). Changes were compared between the field potential (FP) and the amount of histamine released. The results demonstrated that (i) the(More)
A microconcentration concept is proposed to enhance the sensitivity of deoxyribonucleic acid (DNA) hybridization due to evaporation of the hybridization solution on a patterned hydrophobic fluorocarbon polymer (FCP) surface. The combination of microconcentration and hybridization processes provides a tool to manipulate nanoliter solution. To fabricate a(More)
