Abstract:
A signal generating circuit includes: a first signal amplifying circuit arranged to generate a first amplified signal according to a first supply current, a reference signal, and an output signal of the signal generating circuit; a soft-start circuit arranged to generate a control signal according to a soft-start signal; a current controlled circuit arranged to generate the first supply current according to the soft-start signal; and a pass transistor arranged to generate an output signal according to an error amplified signal and the control signal. The error amplified signal is derived from the first amplified signal.
