Description

The continuation cascade is amplified with a negative reversal link, axle, natural key and key actinic ority, and the cathode circuit of the lamim of the cascade of amplifiers.

In the eventual service cascades with actinium and co-artiylionium in the cathode circuit, the input conductance is 1–; ascade has been measured at the terminal of the cathode at the bottom of the cathode. Lodla la mesh lamp.

V), ri aeiioM device, this is the remainder of the disengagement by switching on the dolollltella capacitance between the aode and cathode of the lame of the cascade of condition.

On hertheichrachea scheme “inrcbiiiae foro kas 1: hell of amphells.

The entrance to the cascade of the cascade is connected to the signal point, not shown in the drawing. In the chain lamia 1, the cascade contains cathode 2 controlling weave 3. 3 grid 4. aiod 5 l of lrotinodrolnaya grid 6. The cascade is powered from battery 7. Lagruise 8 is switched on in cell2. Target 9 is the key to the AGC system. leftozaiiyoy ifa drawing. Gelmly luzhet mesh should be included in the cella sieve of Rg.

Solo R, is a common area of both the input and output of the cascade targets. By selecting the magnitude of the solo values R MO; KIIO, it is possible to heal the bosom of the 11th one of the pilot satellites of the cascade with large changes in the displacement of the grid.

Usually, the constant value of the input resistance is obtained only with a sufficiently large value of resistance R.

A large cathode resistance lowers the input conductance of the ipji malix displacements and increases the effect on the electrical capacitance.

If between the aiod and the cathode of the lamina to include an additional capacitance Sr., Then it is possible to obtain the value of the input conductivity at low values of the active distance R.

The current flowing through the capacitance Cp depends not only on the capacitance between the cathode 2 of the lamp 1 And the ground and the resistance RC, but on and on of 1 magnitude of the anode load 8, as a result of which at large anode loads the effect of capacitance 6 increases.

With the use of nentodes, the input conductance of the helmet / can be obtained (and on the order of 150 m it is practically iestable with pzmenepigg iair / keni offset and ranges from 1 to 5 volts.

Subject invention

A cascade of amplification with negative feedback, implemented by including active resistance in the cathode circuit of the amplification cascade lamp, characterized in that between the anode and the cathode of the amplification cascade lamp includes an additional capacitance.
