ISOLATION CIRCUIT WITHOUT ROUTED PATH COUPLED TO ALWAYS-ON POWER SUPPLY

An isolation circuit provided by the present invention includes an inverter and a NOR-gate. The inverter includes an input terminal used to receive an input signal, an output terminal used to output an output signal according to the input signal, and a power terminal coupled to a power supply. The output signal is complementary to the input signal. The NOR-gate is used to perform a logic NOR operation by using the output signal and an isolation control signal to generate a result signal. The NOR-gate includes a first input terminal coupled to the output terminal of the inverter for receiving the output signal, a second input terminal for receiving the isolation control signal, and an output terminal for outputting the result signal. 本发明提出一种隔离电路。该隔离电路包含一个反相器与一个或非门。该反相器包括：用于接收输入信号的输入端、用于根据输入信号输出输出信号的输出端以及耦接至电源的电源端。该输出信号与该输入信号互补。该或非门用于使用该输出信号和隔离控制信号来执行逻辑或非运算以产生结果信号。该或非门包括耦接至该反相器的该输出端并用于接收该输出信号的第一输入端、用于接收该隔离控制信号的第二输入端以及用于输出该结果信号的输出端。
