Abstract- A novel low-voltage two-stage operational amplifier employing resistive biasing is presented. This amplifier implements neutralization and correction common mode stability in second stage while employs capacitive dc level shifter and coupling between two stages. The structure reduces the power consumption and increases output voltage swing. The compensation is performed by simple mill...

Two high performance level restoration circuits are proposed, which outperform the existing level restoration circuits with cross-coupled PMOS, in terms of power dissipation and delay. The first configuration employs a back-bias scheme in order to eliminate the stand-by leakage caused by the low-swing input. The second one adopts a bootstrapping technique, in order to restore the low swing sign...

To perform dynamic tumor tracking (DTT) for clinical applications safely and accurately, gimbaled head swing verification is important. We propose a quantitative gimbaled head swing verification method for daily quality assurance (QA), which uses feature point tracking and a web camera. The web camera was placed on a couch at the same position for every gimbaled head swing verification, and cou...

CONTEXT Low back injuries are the most common injury in golf. Best practice guidelines for rehabilitation and prevention of these injuries are helpful for health care professionals and all golfers. OBJECTIVE To establish a best practice clinical model for low back pain in golfers from diagnosis through treatment and rehabilitation to return to golf. EVIDENCE ACQUISITION The PubMed database ...

We propose capacitively driven low-swing global interconnect circuit using a receiver that utilizes magnetoelectric (ME) effect induced magnetization switching to reduce the energy consumption. Capacitively driven wire has recently been shown to be effective in improving the performance of global interconnects. Such techniques can reduce the signal swing in the interconnect by using a capacitiv...

In Part I a technique for the swing-up control of single inverted pendulum system is presented. The requirement is to swing-up a carriage mounted pendulum system from its natural pendent position to its inverted position. It works for all carriage balancing single inverted pendulum systems as the swing-up control algorithm does not require knowledge of the system parameters. Comparison with pre...

BACKGROUND Minimum toe clearance is a critical gait event because it coincides with peak forward velocity of the swing foot, and thus, there is an increased risk of tripping and falling. Trans-tibial amputees have increased risk of tripping compared to able-bodied individuals. Assessment of toe clearance during gait is thus clinically relevant. In able-bodied gait, minimum toe clearance increas...

Template models can help to demonstrate and prove concepts on human locomotion such as the spring-mass model [1]. Since biarticular muscles may have specific tasks in walking [2], their action during the swing phase is investigated in this study. A new model is presented to describe the swing leg motion (Fig .1). The goal is to identify the role of elastic biarticular muscles on swing leg dynam...

We investigated which of cat limb kinematic variables during swing of regular walking and accurate stepping along a horizontal ladder are stabilized by coordinated changes of limb segment angles. Three hypotheses were tested: 1) animals stabilize the entire swing trajectory of specific kinematic variables (performance variables); and 2) the level of trajectory stabilization is similar between r...
