摘要： Disclosed is a pipelined analog-to-digital converter which includes a digital correction circuit configured to improve the complexity of a logic circuit for dividing a correction period and a no-correction period of a digital output. The pipelined analog-to-digital converter performs a logic correction operation via binary shifting at data error correction. Accordingly, although the resolution increases, it is possible to reduce the complexity and area of a logic circuit.

摘要： Provided is a sensorless BLDC motor system. The sensorless BLDC motor system includes a BLDC motor, a comparator, a motor controller, a three-phase inverter, and a mode selector. The BLDC motor includes first to third coils. The comparator compares a voltage of a specific coil of the first to third coils with a neutral-point voltage to output the compared result. The voltage of the specific coil becomes equal to the neutral-point voltage and a specific time elapses, and then the motor controller generates first and second coil control signals based on the compared result. The three-phase inverter supplies a source voltage or ground voltage to the specific coil, or floats the specific coil, in response to the first and second coil control signals. The mode selector selects a driving mode of the BLDC motor by adjusting the specific time.
