Title: Circuit arrangement for the exponential control of gain
IPC: H03G7/06
Filed: 1975-02-05
Abstract: 1475205 Gain control RFT MESSELEKTRONIK "OTTO SCHON" DRESDEN VEB 5 Feb 1975 [1 April 1974] 4887/75 Heading H3T The gain of a transitor Tr1 which receives an input current Ix and produces an output current Iz depends exponentially on a control voltage Uy applied to the emitters of Tr1 and Tr3 a current equal to the collector current of T3 being supplied to the collector Tr1 by a circuit designated "current mirror". So long as Ix is zero, the collector currents of Tr1 and Tr3 are equal so there is no net output current Iz. A non-zero Ix biases Tr2 to produce a logarithmically related base emitter voltage on Tr2. When Uy is zero, the same base emitter voltage is applied to Tr3 which therefore produces an output current proportional to Ix. When a non-zero Uy is applied the base emitter voltage of Tr1 changes proportionally and the gain changes exponentially. Examples of conventional "current mirrors" which give out currents equal to that put in are given, Fig. 4 (not shown). To control the gain of a plurality of transistors simultaneously a current mirror with a plurality of outputs is provided, Fig. 3 (not shown). A temperature compensated control voltage Uy may be derived from a primary control voltage Uy<SP>1</SP> by the circuit of Fig. 5(a) in which R2 has a resistance proportional to absolute temperature. Alternatively Uy may be derived from an operational amplifier connected as an electrometer and fed by a voltage divider from the primary control voltage Uy<SP>1</SP>.

Abstract: 708,637. Valve circuits. GENERAL ELECTRIC CO., Ltd., and FAITHFULL, P. J. F. Jan. 17, 1952 [March 1, 1951], No. 5004/51. Class 40 (6) The decoupling point of a valve electrode is connected by a feedback impedance to the decoupling point of an electrode of a previous valve fed from the same supply and at which the voltage variations are of opposite phase, the phase angle of the feedback impedance being equal to the phase angle of the impedance as measured at the first mentioned decoupling point looking towards the supply source. Phase changes due for example to ineffective low frequency decoupling at the earlier decoupling point may thus be reduced. The anode decoupling points 11, 12 are connected by an R.C. feedback network 25, 26 the phase angle of which is equal to the phase angle of the apparent impendance of the supply source as measured between the negative terminal and point 12 (i.e., the impedance of resistor 21 and decoupling capacitor 22 in parallel when the supply source has zero impedance). It is shown that if R25=(k-1) R21 and C26= C22/(k-1) where k is the current gain of the second valve, the point 11 is at zero signal voltage and the decoupling network 23, 24 of the first valve may be removed the H.T. current being supplied through resistor 25, Fig. 2 (not shown). This decoupling network, if retained however should have a phase angle equal to that of the other decoupling network (21, 22) and should preferably have the same impedance.

Abstract: 571,462. Wireless receiving circuits. LIPS, J. Nov. 26, 1943, No. 19764. Convention date, Nov. 10, 1942. [Class 40 (v)] A short-wave adaptor includes a mixeroscillator which, during reception of long and medium waves, is used as an aperiodic amplifier. In the Figure the short-wave adaptor is shown in the position for receiving short-wave signals. With switch S2 in the left-hand position, aerial A is connected to a short-wave coil L1 coupled to ooil L2 which, with one of the condensers C1, C3, C5, forms an input circuit tuned to the mid-frequency of one of the short-wave bands, selection being made by switch S1. The input circuit is coupled through a small condenser Cs to the grid of the hexode portion of a triodehexode frequency changer MR. The triode portion is arranged as an oscillator having a tuned circuit formed from an inductance L4 and one of the condensers C2, C4, C6 selected by switch S3. Switch S3 is operated in cooperation with wave-band switch S1 so that, for each short-wave band, there is provided at the anode A1 an intermediate frequency-which lies within the reception range of the receiver (not shown) with which the adaptor is designed to co-operate. This intermediate frequency is fed through condenser C9 and lead AK to the input terminal of the receiver, and tuning to the individual stations in each short-wave band is effected by the normal tuning means of the receiver, and gives a partial band-spreading effect. For receiving long or medium waves, switch S2 is moved to the right-hand position to connect the aerial A to the grid of the hexode portion of MR which now acts -as a highfrequency amplifier. Condenser Cs is too small to byepass the long and medium frequencies. The oscillator portion is inoperative during the reception of long and medium waves.
