Abstract: An amplifier includes a subtracting unit for generating an error signal according to an input signal and an output signal; a noise shaping unit for executing a noise shaping operation on the error signal to produce a noise-shaped signal; a pulse adjustment unit for generating a control signal according to the noise-shaped signal and the input signal; and a power stage for generating the output signal according to the control signal.

Abstract: An application circuit for shaping noises and method thereof involve an analog-to-digital converter which converts a first analog signal into an n-bit digital signal for an encoder to generate a p-bit digital signal. Then a control circuit generates a plurality of control signals based on the p-bit digital signal, wherein p is two to the power of n minus one, and n is an integer greater than one. Each of the (2n?1) unit elements with element mismatch in an internal n-bit digital-to-analog converter executes the digital to analog conversion in response to the corresponding control signal, thereby generating a second analog signal, and an adder outputs the first analog signal based on the second analog signal and a third analog signal.
