The present invention discloses a demodulating method for a demodulating circuit. The demodulating method comprises a step of utilizing a wave-shaping voltage step-down circuit to perform a wave-shaping process for a modulating input signal. A separate circuit of modulating input signal is filtering data zero of the modulating input signal and reserving data one of the modulating input signal. A triggering circuit of data recover is used to start the count of data span, until the data count is completed. A data recover circuit is used to recover the data.

Demodulating circuit and the method thereof

The present invention discloses a feedback type voltage regulator, including a voltage reference circuit for providing a reference voltage, distributed series feedback amplifiers electrically coupled to the voltage reference circuit and a power transistor which gate is electrically connected to the distributed series feedback amplifiers. The distributed series feedback amplifiers comprises three set of amplifiers serially connected with each other, wherein the relation of the gain of the first amplifier (A1), the second amplifier (A2), and the third amplifier (A3) is A1&#x3e;A2&#x3e;A3, wherein the relation of the bandwidth of the first amplifier (B1), the second amplifier (B2), and the third amplifier (B3) is B1&#x3c;B2&#x3c;B3.
