Abstract
A non-linear analog signal conversion circuit configured of passive elements and a lighting apparatus using the same. The non-linear analog signal conversion circuit includes: an input module for inputting a dimming signal; an inversion module for inverting the dimming signal; a non-linear conversion module for non-linearly converting input power Vinto first output power Vaccording to the inverted dimming signal; and a filter module for converting the first output power Vof an output terminal of the non-linear conversion module into reference power Vby removing noise of the first output power V.
