摘要： A control circuit for a main switch is provided. The control circuit includes an output voltage tracker, a main switch bias generator, and a reference current device. The output voltage tracker is coupled to the main output end and generates a first tracking voltage positively correlated to an output voltage. The main switch bias generator, in response to the first tracking voltage, generates a second tracking voltage substantially equal to the output voltage. The reference current device is coupled to the main switch bias generator and is used to generate a control voltage on a main control end. The reference current device is used to limit the maximum value of the output current. The main switch and a duplicating switching element of the main switch bias generator form a current mirror configuration circuit. The consuming current of the output voltage tracker is positively correlated to the output current.

摘要： Successive approximation ADC includes a digital-to-analog converter, a comparator, a comparison unit, a timing unit and a control logic circuit. The digital-to-analog converter converts a digital signal to a reference analog signal. The comparator compares an analog input signal with a reference analog voltage and generates a comparing signal. The comparison unit generates a comparison result signal according to the comparing signal. The timing unit generates a clock signal, and sequentially enables N supplementary clock signals corresponding to N bits when the comparison result signal is enabled. The control logic circuit updates the digital signal according to the comparing signal, and generates N bits of digital value sequentially from the most significant bit to the least significant bit, and then determines whether the digital value is valid according to whether the Nth supplementary clock signal corresponding to the least significant bit is enabled.
