چکیده
A passive piecewise-linear function approximation circuit with current input and output is presented. The gain of the circuit is controlled by switching diodes. The breakpoints and slopes of its inputoutput characteristic are set by resistances. Relations for computation of these resistances are given. As an application of the proposed circuit, a triangle to sine wave shaper is shown. Computer simulation confirmed a good functionality of the circuit even at high frequencies. Key-Words: Piecewise-Linear Function Approximation Circuit, Wave Shaping Circuit, Current Mode

متن کاملAn Isolated Off-Line High Power Factor Electrolytic Capacitor-Less LED Driver with Pulsating Output Current
One of the most efficient lighting technology is based on light-emitting diodes (LEDs). Common LED drivers with AC-input (50-60Hz) usually require a bulk electrolytic capacitor to decrease low-frequency ripple in the output. However, the critical element that limits the lifespan of the LED driver is the electrolytic capacitor. An isolated off-line LED driver is proposed in this paper, in which ...
