چکیده
In this work a new resistorless sub-bandgap voltage reference topology is presented. It is a self-biased and small area circuit that works in the nano-ampere consumption range, and under 1 V of power supply. The behavior of the circuit is analitically described, a design methodology is proposed and simulation results are presented for a standard 0.18 μm CMOS process. A reference voltage of 463 mV is demonstrated, with a temperature coefficient of 8 ppm/C for the 0 to 125 ◦C range, while the power consumption of the whole circuit is 8.25 nW under a 0.75 V power supply at 27 C. The estimated silicon area is 0.0043 mm.

Lactate dehydrogenase and caspase activity in nasopharyngeal secretions are predictors of bronchiolitis severity
BACKGROUND Bronchiolitis is the leading cause of hospitalization in infants. Biomarkers of disease severity might help in clinical management. OBJECTIVE To determine the clinical predictiveness of NW-LDH, NW-caspase 3/7, and NW-LDH/NW-caspase 3/7 ratio in bronchiolitis. METHODS Previously healthy children less than 24 months of age with bronchiolitis were recruited from the Texas Children's...
متن کاملAccelerated contractile function and improved fatigue resistance of calf muscles in newborn piglets with IUGR.
Asymmetrical intrauterine growth restriction is denoted by disproportional reduction of muscle mass compared with body weight reduction. However, effects on contractile function or tissue development of skeletal muscles were not studied until now. Therefore, isometric force output of serial-stimulated hindlimb plantar flexors was measured in thiopental-anesthetized normal weight (NW) and intrau...
متن کاملMonolithic barrier-all-around high electron mobility transistor with planar GaAs nanowire channel.
High-quality growth of planar GaAs nanowires (NWs) with widths as small as 35 nm is realized by comprehensively mapping the parameter space of group III flow, V/III ratio, and temperature as the size of the NWs scales down. Using a growth mode modulation scheme for the NW and thin film barrier layers, monolithically integrated AlGaAs barrier-all-around planar GaAs NW high electron mobility tran...
