    Abstract: A low pass filter (100) includes a first amplifier stage (110) and a second amplifier stage (120). The first amplifier stage (110) includes a differential operational amplifier (130), wherein the first amplifier stage is arranged to process a differential input signal to generate a differential intermediate signal, the differential input signal having a first input signal (DIN1) and a second input signal (DIN2), and the differential intermediate signal having a first intermediate signal (DM1) and a second intermediate signal (DM2). The second amplifier stage (120) has no common-mode feedback and is arranged to process the differential intermediate signal to generate a differential output signal, wherein the differential output signal has a first output signal (DOUT1) corresponding to the first input signal (DIN1) and a second output signal (DOUT2) corresponding to the second input signal (DIN2). Since the noisy common-mode feedback is removed from the second amplifier stage, the overall common-mode noise of the low pass filter can be decreased.
