MULTIPHASE OSCILLATOR WITH 40% SPREAD SPECTRUM FREQUENCY MODULATION AND 250KHZ OUTPUT FREQUENCY

MULTIPHASE OSCILLATOR WITH 40% SPREAD SPECTRUM FREQUENCY MODULATION AND 250KHZ OUTPUT FREQUENCY

This is a precision, low power, and easy-to-use oscillator that provides multiphase outputs. The output frequency of the project is set to 250Khz, with 40% spread spectrum. The oscillator frequency can be set by resistor R1, and the spread spectrum can be changed using R3. The master oscillator is controlled by the RSET resistor R1 and has a …

Researchers develop LED covering full visible light spectrum

LED and OLED lighting, which is generally called solid-state lighting (SSL), is becoming more common as the next generation lighting. Evaluations of total luminous flux (a performance index for lighting) and color are important for SSL, and to evaluate those values, it is indispensable to measure the light intensity of each wavelength accurately based on …
