Abstract
A signal modulating device includes: an integrating circuit arranged to generate an integrated signal according to a scaled analog signal and a first feedback signal; a resonating circuit arranged to generate a resonating signal according to the integrated signal; a first signal converting circuit arranged to convert the resonating signal into a digital output signal; a second signal converting circuit arranged to convert the digital output signal into the first feedback signal; and a first impedance circuit having a first terminal receiving an analog signal and a second terminal coupled to the resonating circuit for altering the location of zeros in the forward-path transfer function and consequently shaping the signal transfer function (STF) of the signal modulating device; and a second impedance circuit having a first terminal receiving the analog signal and a second terminal coupled to the integrating circuit for generating the scaled analog signal.
