This disclosure is directed to techniques for preventing or reducing perturbations of an output signal of a differential amplifier caused by ionizing radiation incident upon the amplifier. The amplifier may include an amplification module that includes a plurality of amplification units configured to amplify a difference between a first component and a second component of a differential voltage signal to generate a plurality of amplified difference signals each corresponding to the amplified difference. The amplifier may further include a combination module that combines the plurality of amplified difference signals to generate a common output signal corresponding to the amplified difference.
