Abstract :
In this work, we present a single-chip design for the three-phase brushless DC motors (BDCM) system, and which is implemented by a 0.35 μm 3.3 V CMOS process. A mixed-signal IC will be accomplished by the implementation of analog circuit and digital circuit in the same chip. Eventually, this chip system includes an analog circuit (Hall signal amplifier), a digital circuit (logic process block), and a frequency voltage converter (FVC) to complete the control & driving circuits. Meanwhile, experimental results are included to verify the proposed scheme and the real measurement fit theoretical analysis well.
