Title: Improvements relating to charging and/or discharging circuits for condensers
Inventor: HUNTLEY KEITH GORDON
IPC: G06G7/186
Filed: 1952-10-17
Abstract: 761,853. Systems of charging and discharging condensers. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Sept. 21, 1953 [Oct. 17, 1952], No. 26039/52. Class 38 (4). [Also in Group XL (c)] In a circuit for charging or discharging a capacitor 4 an amplifier 1 is provided with negative feedback 23 to lower the output impedance so that the capacitor is charged or discharged through it to a level dependent on the input 19 to the amplifier 1 when switches 21, 22 are operated. A signal is applied over terminal 6 and resistor 5 through a switch 7 to the amplifier 1, the time integral appearing at terminal 11, the switches 21, 22 being held in the open position. When the circuit is to be reset, a pulse source 9 opens switch 7 and pulse source 10 causes diodes 26, 28 to conduct so that the capacitor 4 is connected between terminal 11 and earth. At the same time switch 21 is closed to connect the feedback loop resistor 23 in circuit together with resistor 20. The potential of terminal 11 rapidly assumes a level dependent on the potential applied to terminal 19. The capacitor 25 is included to block D.C. potentials and resistor 24 improves stability by reducing the effect of the secondary feedback path over capacitors 4, 25 and the finite resistance of switch 22. In a modification, Fig. 4, the input to the amplifier 1 is fed over a cathode follower 70 with stabilizing components 72, 73, 74. The extra feedback path over capacitor 81 limits the re-setting rate and prevents overload of the amplifier 1. Capacitors 82, 83 are included to reduce phase shift due to stray capacities. In a modification, Fig. 3, a switch of the type described in Specification 738,827, [Group XL (c)], is employed to establish a potential at terminal 11 corresponding to input signals applied at terminals 40, 50 and 60. If the inputs are sinusoidal, the pulses from sources 45, 55 and 65 may be phased to occur at the peak of the input so that each valve 41, 51 and 61 is rendered operative correspondingly the switches 21, 22 being closed at each occurrence. When valve 41 is conductive, resistors 42, 43 are effective in conjunction with amplifier 1 to give a low output impedance so that the potential across capacitor 4 changes rapidly. This potential is retained until the next valve 51 is rendered operative. The selector switch may be omitted when a single input only is employed. Specification 580,527, [Group XL], also is referred to.
