It is considered the problem of synthesis of structural and schematics of bipolar analog ICs based on the classic “folded” cascode which have a small zero-level (offset voltage, Vov) and its drift in the terms of temperature and radiation effects. Thus the basis of the modernization of the scheme are adopted by well-known basic analog IC (operational amplifiers, continuous stabilizers, voltage comparators, etc.), in which by the rules set forth below, we introduce some structural redundancy, which provides a decrease Vov and its voltage drift effect on one or two orders).

A Leaky-wave antenna based on a covered rectangular waveguide with partially dielectric filling and transverse slots is investigated. The complex propagation constant is defined by matching of magnetic field in slots. A velocity factor dependences on the waveguide filling parameters are presented. The influence of the dielectric position in the waveguide on the antenna characteristics is considered. The radiation pattern is analyzed. A pattern tilt angle, an optimal antenna length and a first null beamwidth are defined.

Summary form only given: The problem of regulation for a DC motor with autonomous voltage inverter is discussed. The considered control system consists of two feedback loops. In the first one, the armature current control for a DC motor is provided by means of pulse-width modulated control of autonomous voltage inverter. In the second one, DC motor speed control is maintained. Proportional-integral (PI) controllers are designed for armature current and motor speed control based on singular perturbation technique such that multi-time-scale motions are artificially induced in the closed-loop system.
