英文摘要	currently, the on-chip wireless communication system(owcs) includes 2nd-generation (2g), 3rd-generation (3g), and long-term evolution (lte) communication subsystems. to improve the power consumption of owcs, a typical architecture design of system power control unit (spcu) is given in this paper, which can not only make a 2g, a 3g, and an lte subsystems enter sleep mode, but it can also wake them up from sleep mode via the interrupt. during the sleep mode period, either the real-time sleep timer or the global system for mobile (gsm) communication sleep timer can be used individually to arouse the corresponding subsystem. compared to previous sole voltage supplies on the owcs, a 2g, a 3g, or an lte subsystem can be independently configured with three different voltages and frequencies in normal work mode. in the meantime, the voltage supply monitor, which is an important part in the spcu, can significantly guard the voltage of owcs in real time. finally, the spcu may implement dynamic voltage and frequency scaling (dvfs) for a 2g, a 3g, or an lte subsystem, which is automatically accomplished by the hardware.
