The radiation-hardened microcircuits of the multichannel op amps with current feedback and the analog interfaces based on the structured array MH2XA010

The article presents functional schemes of two IP-modules included into a new (2016) radiation-hardened structured arrays (SA) MH2XA010. The microcircuits of the main modifications of op amps (OAs) with current negative feedback (CNF) can be realized on the base of SA (due to the interconnection wiring of elements). The terminal parameters of op amps are considered, the practical recommendations for choosing the steady-state behaviors, the active and passive elements of SA, providing the peak values of the slew rate and the upper frequency limit of op amp in a wide range of changes of transfer ratios are given. The properties of a new subclass of op amps based on SA MH2XA010 — circuits with the so called generalized current negative feedback, combining the properties of classical op amps with voltage feedback and op amps with CNF are examined.
