| 主权项 | 1. A logic inverter with over-current protection, comprising: a transistor; an input signal line coupled to a gate terminal or base region of the transistor; an output signal line coupled to a drain terminal or emitter region of the transistor; a power supply line coupled to the drain terminal or emitter region of the transistor; and a feedback resistor between a source terminal or collector region of the transistor and ground, wherein an impedance value Rf of the feedback resistor satisfies the following equation: VIH−Vth<Rf·Id,max where VIH is a voltage corresponding to a logic high of the input signal, Vth is a turn on voltage of the transistor, and Id,max is a maximum channel current through the transistor. | ||
