Abstract
An amplifier transistor has its base-to-collector voltage maintained substantially zero, and its collector-base junction has in inverse-parallel connection therewith an auxiliary semiconductor junction exposed to the same transient ionizing radiation environment. Photo-currents generated in the collector-base junction of the amplifier transistor responsive to transient ionizing radiation are counteracted by the photo-currents concurrently generated in the auxiliary semiconductor junction, so amplification can continue without being unduly hampered by such radiation.
