| Abstract: | A new type of pulse-width-modulation (PWM) unit constructed with CMOS logic circuits is presented in thepaper.The structure of the unit is given and its functions are described.The relationship between the logic controllabilityof the charging passage and the rising time of the voltage at the output terminal has been simulated using SPICE analysis.Process parameters for standard CMOS IC's are also given. The PWM unit can be used in smart power IC' s to makePWM technique become digitalized. |
