Abstract
A pulse width modulation signal phase shift circuit based on 1.5 μm BiCMOS process was designed. This circuit can be used in LED driver chip to shift the phase of the dimming PWM signal. The circuit had three different modes to be adapted in different situation, shifting 0° , 180° or any degree of phase. The test results show that, at 100 Hz to 20 kHz PWM signal, (he circuit' s three modes work fine with precision and stability.关键词
