半导体装置
摘要：
本发明涉及一种半导体装置。根据一个实施例，半导体装置包括：第一开关(SWx)，其切换是否供应通过积累电源(10)输出的电荷而产生的第一电源电压(Vx)，作为至第一电路(13)的第二电源电压(VDD)；以及第二开关(SW1)，其切换是否将抑制第二电源电压(VDD)波动的平滑电容器(C1)连接至第一电路(13)，并且第一开关(SWx)响应于第一电源电压(Vx)已经达到足够的电压而切换至导通状态，并且随后第二开关(SW1)响应于第二电源电压(VDD)已经达到足够的电压而切换至导通状态。
摘要（英）：

According to one embodiment, a semiconductor device includes: a first switch SWx which switches whether or not to supply a first power supply voltage Vx generated by accumulating a charge outputted from a power source 10, as a second power supply voltage VDD to a first circuit 13, and a second switch SW1 which switches whether or not to connect to the first circuit 13 a smoothing capacitor C1 which suppresses a fluctuation of the second power supply voltage VDD, and the first switch SWx is switched to an on state in response to that the first power supply voltage Vx has reached a sufficient voltage, and then the second switch SW1 is switched to the on state in response to that the second power supply voltage VDD has reached a sufficient voltage.
