    • An inverter circuit (500) having a drive transistor (102) that operably couples to a voltage bias input (101) (and where that drive transistor controls the inverter circuit output by opening and closing a connection between the output (105) and ground (104)) is further operably coupled to a feedback switch (401). In a preferred approach the feedback switch is itself also operably coupled to the voltage bias input and the output and preferably serves, when the drive transistor is switched “off,” to responsively couple the voltage bias input to the drive transistor in such a way as to cause a gate terminal of the drive transistor to have its polarity relative to a source terminal of the drive transistor reversed and hence permit the inverter circuit to operate across a substantially full potential operating range of the drive transistor.
    • 一种具有可操作地耦合到电压偏置输入(101)的驱动晶体管(102)的逆变器电路(500),并且其中该驱动晶体管通过打开和关闭输出(105)和地( 104))进一步可操作地耦合到反馈开关(401)。 在优选的方法中,反馈开关本身也可操作地耦合到电压偏置输入端和输出端,并且优选地在驱动晶体管被切断时关断,以将电压偏置输入以驱动晶体管的方式耦合到驱动晶体管, 以使驱动晶体管的栅极端子相对于驱动晶体管的源极端子的极性相反,从而允许逆变器电路在驱动晶体管的基本上全部的电位工作范围内工作。
