Signal generating apparatus for generating power-on-reset signal
A signal generating apparatus, for generating a power-on-reset signal, including a bias circuit and a power-on-reset signal generating circuit is disclosed. The bias circuit is for generating an output bias voltage, and includes at least one bipolar junction transistor (BJT), wherein a base terminal of the BJT is coupled to a collector terminal of the BJT, and the output bias voltage is related to an emitter-to-base voltage of the BJT. The power-on-reset signal generating circuit is coupled to the bias circuit, and is for generating a duplicated voltage by duplicating the output bias voltage, wherein the power-on-reset signal is generated according to the duplicated voltage.
