supply to peripheral devices; modern versions of the standard extend the power delivery limits for battery charging and devices requiring up to 240 watts
imaging. The two main types of electronic image sensors are the charge-coupleddevice (CCD) and the active-pixel sensor (CMOS sensor). Both CCD and CMOS
electricity to portable devices. Inductive charging is also used in vehicles, power tools, electric toothbrushes, and medical devices. The portable equipment
cross-coupled circuit is parasitic capacitance rather than switching threshold voltage. The losses occur because some of the energy has to go into charging
