An apparatus for effecting signal chopping in an amplifier device having an amplifier section, a modulation section, a ramp generating section and a clock section includes: at least one signal treating unit coupled among the clock section, the amplifier section and the ramp generating section. The at least one signal treating unit cooperates with the clock section to effect providing a chopping signal to the amplifying unit at a chopping frequency and to effect providing a ramping signal at a ramping frequency to the ramp generating section. The chopping frequency is neither a fundamental frequency nor a harmonic frequency of the ramping frequency.
