Configurable structured array for fabrication of radiation-hardened analog interfaces

Abstract

The design of a new configurable structured array (CSA) is considered. The CSA is intended for development of multichannel (up to eight channels) integrated circuits of the analog interfaces of sensors. An example of operational amplifier is used to show that circuit synthesis with allowance for radiation-induced variations in characteristics of complementary bipolar transistors may provide minor degradation of parameters of the analog ICs after ionizing irradiation. Electrical schemes of the CSA analog components and experimentally measured parameters are presented.
