    • The level shifter circuit includes a low-voltage operating inverter INV4, a high-voltage operating inverter INV5, NMOS transistors NT5 and NT6 and a PMOS transistor PT3. The output from low-voltage operating inverter INV4, the source of NMOS transistor NT6 and the gate of PMOS transistor PT3 are joined. The input to high-voltage operating inverter INV5, the drain of NMOS transistor NT6 and the source of NMOS transistor PT5 and that of PMOS transistor PT3 are joined. The drain of NMOS transistor NT5 and the gates of NMOS transistors NT5 and NT6 are connected to the power feed line of a high-voltage power source. The input to low-voltage operating inverter INV4 forms an input signal terminal Vin2 while the output from high-voltage operating inverter INV5 forms an output signal terminal Vout2.
    • 电平移位器电路包括低电压工作反相器INV4,高电压工作反相器INV5,NMOS晶体管NT5和NT6以及PMOS晶体管PT3。 来自低电压工作逆变器INV4,NMOS晶体管NT6的源极和PMOS晶体管PT3的栅极的输出被连接。 高电压工作逆变器INV5的输入,NMOS晶体管NT6的漏极和NMOS晶体管PT5的源极和PMOS晶体管PT3的输入相连接。 NMOS晶体管NT5的漏极和NMOS晶体管NT5和NT6的栅极连接到高压电源的馈电线。 低电压工作逆变器INV4的输入形成输入信号端子Vin2,而高电压工作逆变器INV5的输出形成输出信号端子Vout2。
