Capacitive touch switches work by measuring the change in capacitance of a PCB (printed-circuit-board) pattern depending on the placement of a user’s finger over a sensing pad. Capacitive switches are ...

CMOS relaxation oscillators have emerged as a pivotal technology in modern integrated circuits, offering a balance between low power consumption and simplicity of design. These oscillators utilise the ...

A relaxation oscillator is an oscillator based upon the performance of a physical system’s resending to equilibrium after being disturbed. It is a dynamical system within the oscillator continuously ...

The National University of Singapore and Politecnico di Torino teamed up at ISSCC 2021 to describe a capacitive sensor interface designed to run from harvested energy, needing only a supply voltage ...
