ABSTRACT

The goal of this thesis is to design a three phase BDCM driving IC and reduce system cost by using a CMOS process. The

advantage of CMOS process is low cost, low power dissipation and high integrated density. The rotor position feedback Hall signal amplifier, driving signal generator, FVC ( Frequency to Voltage Converter ) and PWM ( Pulse Width Modulator) building speeding control system and over temperature protecting block were built in this system. Eventually, a SOC or mixed-signal IC will be accomplished, in which the analog circuit and digital circuit were included in the same chip. All the system function blocks in this thesis have been simulated by the transistor level simulation EDA tools. And, the simulation and testing results of this smart power module will discuss latter.
