The mathematical basics of the non-classical approach to the logical synthesis of k-valued digital structures based on the replacement of the classic mathematical apparatus of logic synthesis (Boolean algebra) to the proposed mathematical apparatus — linear algebra are considered. The logic synthesis process of two valued and multi-valued digital structures in linear algebra including the formation...
The paper reviews the features of the advanced high-frequency correction circuit for the resistive voltage dividers (attenuators, AT) operating on the capacitive load. The effect of the constant cutoff frequency of considered AT is shown at changing transfer ratio in a wide range. This feature of the considered circuit is the main advantage over the classical AT implementation for the analog-to-digital...
Microwave selective amplifiers (SA) with paraphase output that provide high Q-factor and voltage gain (K0) on quasi-resonance frequency f0 at low parametric sensibility are considered. The results of the mathematical analysis and simulation of SA on 0.25 µm SiGe process are given. Presented SA, along with selective properties has phase splitter feature and allow current control of Q-factor.
The circuit design features of classical stages (common-base (CB), common-emitter (CE)) and voltage follower with a capacitive load with bandwidth enhancement technique based on the effect of the mutual compensation of the parasitic impedances are considered. The technique is based on introduction of special circuits of active frequency correction, such as current and voltage followers. The advantage...
Analysis of architectural and circuit limitations onvoltage gain (Gain) of the classical stages with a common baseand a common emitter at a low-voltage supply are considered.It is also considered methods of improving voltage gain whichare based on the principles of their mutual compensationimpedances that have a negative impact on voltage gain. Themathematical conditions of presented methods are alsoconsidered...
