Abstract : This thesis examines and discusses the use of Composite Operational Amplifiers to reduce the sensitivity of active circuits to the degraded performance of individual devices after exposure to radiation damage. Composite operational amplifiers, known to provide enhanced stability, decreased sensitivity to circuit element variations and an extended operation frequency range, can be used to reduce circuit performance dependence on individual device parameter degradation under radiation without the use of radiation hardened devices. If radiation hardened devices are used in the composite operational amplifiers, it should be possible to achieve even higher levels of insensitivity to radiation. The composite operational amplifier is the only generalized method known to provide radiation damage protection in this manner for active linear networks.
