A buck converter is a step down DC/DC converter used in portable electronic devices to convert higher DC voltages to small voltages necessary to function. Lossless load current sensing ability is one of the most desirable features of contemporary current or voltage mode controlled DC/DC converters. Recently, current sensing techniques in DC/DC converters...

Despite recent progress in prosthetic science, 38% of artificial limb users ultimately reject their limb. This is mostly due to the quality of sensation and control. There are more than 1.7 million people with limb loss in the US with more than 185,000 new amputations each year. The development of a more responsive prosthesis communication interface...

Before converting detected power levels to the digital domain, conventional antenna tuning systems couple incident and reflected powers through a three-line directional coupler in addition to two RF power detectors. Replacing these conventional antenna tuning systems with the automatic antenna matching techniques and devices employed at lower radio...

For mobile devices, reducing power draw and prolonging battery life are critical design objectives. Presently, current-steering digital to analog converters (DACs) require high power consumption and dynamic element matching and are vulnerable to component source mismatch. Accordingly, large rail devices and higher supply voltages are needed. Additionally,...
