In this paper, it was supposed to current mode design included to required current of ideal LED, through asymptotic method for LED driving. LED`s current characteristic has exponential function, and implementation of driving circuit exists problems. However, it can be designed to linear current source through asymptotic method for ideal required current Proposed LED driving circuits was confirmed the linearity to switched input constant current sources, and driving circuits was designed to satisfy the LED current requirement. Proposed circuit has LSB corresponding to 800μA in 9.6um width and confirmed by Dong-Bu 0.35um CMOS process.
