چکیده
The environment development for deep sleep has been studied using analysis results of the big data about parameters in the bedroom. The organic light emitting diode (OLED) illuminations of the bedroom are dimming using analysis results of the big data. Therefore, a low-power and compact design of dimming part is required for OLED system. In this paper, the miniaturized control block of the clock cut-off circuit was designed using De Morgan’s laws with adiabatic dynamic CMOS logic (ADCL) digital 3-bit PWM. The designed control block pauses the D-ffs after cutting off the clock at both dimming 0 % and 100 % of PWM output. The operation of control block is confirmed by post-simulation using hspice with Rohm 0.18um standard CMOS model. As a result 10 transistors of the miniaturized control block were reduced.
