Title: Signal translating system
IPC: H03F3/195
Filed: 1965-09-14
Abstract: 1,127,801. Amplifiers. RADIO CORPORATION OF AMERICA. 14 Sept., 1965 [14 Sept., 1964], No. 38257/65. Heading H3T. An amplifier comprises two transistors with a common emitter resistor, the collector of one having as load a resistor of twice the value of the common emitter resistor and being directly connected to the base of a third transistor which is an emitter-follower. Fig. 5 shows an amplifier for the intercarrier sound signal in a TV receiver, with a tuned input circuit 70, the components inside the dashed line being formed on one chip of material. The amplifier comprises three stages according to the invention, the output from the last stage being passed to an F.M. discriminator 110/116. Each stage comprises an emitter-coupled pair 74/76, 82/ 84, 102/104 with the emitter resistor of half the value of the collector load of the second transistor; it is shown that this arrangement stabilizes the circuit against changes in temperature and power supply. The second transistor of each stage is directly coupled to the base of an emitter-follower 78, 86, 106 which feeds the following stage. The emitters of the third transistors are returned to points more negative than the bases of the second transistors so that the D.C. levels of these bases will be the same as those of the emitters of the following third transistors, and hence the same as the inputs to the succeeding stages. By this means coupling capacitors and complicated biasing networks are avoided. In the circuit shown, the base of transistor 76 is coupled to the emitter of 86 to provide D.C. feedback for further stabilization. Unbalance due to the base current of 76 flowing through the emitter resistor 96 of 86 is avoided by providing further resistors 88, 94 such that the voltages across these are equal and opposite. The first two stages 74-86 are supplied with a regulated voltage through resistor 138 and diodes 140-150, the latter providing a constant voltage drop. To reduce the impedance of the rectifier chain, and hence variation in load current when amplitude modulation is present, the amplifying transistors may be connected to the diodes through emitter-followers (Fig. 6, not shown). The capacitor 90 provides negative feedback at low frequencies and hence gives a band-pass effect in the amplifier, but for other applications this may be replaced by a resistor to give a level response up to the point where stray capacitances are appreciable. Alternatively, a series resonant circuit here will give a selective amplification around the resonant frequency. The integrated circuit and biasing means form the subject of Specification 1,127,802.
