Abstract

575,250. Valve amplifying and generating circuits. COSSOR, Ltd., A. C., and WHITELEY, J. W. Feb. 17, 1942, No. 2100. [Class 40 (v)] An integrating or differentiating circuit comprises a degenerative feedback amplifier having a differentiating or integrating, network in the feedback path so arranged that the voltage fed back is nearly equal in amplitude to the applied voltage. In this way, the voltage fed back represents either the rate of change in the output voltage or the time integral of the output voltage. Fig. 1 shows a linear voltage sweep generator having a degenerative feedback consisting of a differentiating time constant network 4, 5 so that a voltage proportional to the rate of change in anode voltage is fed to the grid in opposition to a constant source. The voltage sweep is initiated when switch 6 is opened, the condenser 5 then being charged and subsequently discharged through the valve reducing the anode voltage and producing a voltage across resistance 4 slightly greater than the opposing positive voltage applied at X. The voltage across condenser 5 falls at a constant rate until a low limiting value is reached when operation of the switch 6 recharges the condenser and causes the operation to be repeated. In a modification, Fig. 2 (not shown), the point X is connected to a point of negative potential and the condenser 5 is charged during the sweep in which case an inverted diode is connected to the control grid to discharge the condenser when switch 6 is closed. To increase the accuracy of differentiation, a multi-valve amplifier may be used, Fig. 3 (not shown), with the source connected to the input through a resistance which with an inductance in the feedback path forms the integrating time-constant network. Fig. 4 shows an integrating amplifier with a differentiating time-constant network 4, 5 and further compensation by the use of cathode follower 11 which applies potential variations to the input terminal 14 so that the potential difference across resistance 4 nearly equals the potential applied to the input terminals 13, 14. A generator similar to that shown in Fig. 1 may have internal means of re-establishing the discharge of the condenser 5 as shown in Fig. 5. A pentode valve is used with the screen and suppressor grids coupled by condenser 8 and resistances 9, 10 included in the supply leads so that condenser 5 is charged by the cutting off of the anode current through the anode load resistance 2 and by grid current. The circuit may be arranged to be self-running or be synchronized by a tripping pulse applied through a condenser to the suppressor grid. Alternatively, the switch 6 may be replaced by a mechanically driven commutator or an electrical discharge circuit, using a gas discharge triode or hard valves.
