An integrator is described that may include a level-shifting capacitor, a feedback capacitor, a pre-amplifier stage and a multi-path amplifier module. The integrator may have inputs for connected an input signal source to the level-shifting capacitor. The level-shifting capacitor is connected to an input of a pre-amplifier stage of an integration signal path and to the input. The level-shifting capacitor may level shift the voltage at the input of the circuit to a lower voltage at the input of the pre-amplifier stage. Thereby, the supply voltage to the pre-amplifier stage may be reduced as well as have limited power consumption, limited temperature rise, and reduced noise that may be attributed to any thermal effects.
