Differential Tissue‐Coupled Powering for Battery‐Free Injectable Electroceuticals

Advanced Science, EarlyView.
A thread‐like injectable neural stimulator is powered through differential tissue‐coupled powering (DTCP), which harvests RF‐frequency tissue potentials with an elongated receiver while preserving a injectable cross‐section. The system integrates an ASIC, stimulation electrodes, and a portable transmitter, enabling wireless peripheral nerve stimulation,

Frequency-Locked Loops in Electrical Power and Energy Systems: Equivalent or Different to Phase-Locked Loops?

IEEE Industrial Electronics Magazine, 2021
In the electrical power and energy (EPE) area, the traditional concept in designing the synchronization system of power converters is using the phase-locked loop (PLL) concept. An alternative way is using the frequency-locked loop (FLL) concept, which is also known as the adaptive notch filter, adaptive noise cancelation technique, gradient descent ...

A frequency steered phase locked loop

1997 IEEE International Performance, Computing and Communications Conference, 1997
Voltage controlled oscillators (VCOs) implemented in digital VLSI IC (integrated circuit) technology typically have very poorly controlled centre frequencies and poor phase noise characteristics, thus severely limiting their use in phase locked loop (PLL) applications.
