Abstract
1338487 Transistor amplifying circuits MEDICOR MUVEK 12 May 1971 [12 May 1970] 14592/71 Heading H3T In a cascode amplifier the base of the transistor 6 in common base connection is biased from a tap on a potentiometer, as shown comprising resistors 8, 9 connected between the supply terminal 3 and the collector of the transistor 5 in common emitter connection. The arrangement is intended to produce an output voltage at terminal 4 which is twice the allowable collector to emitter voltage of a single transistor, and the collector voltage of the transistor 5 is limited to half the supply voltage by means of a diode 11 and potentiometer comprising equal resistors 12, 13. Two such cascode amplifiers may be provided with a common emitter impedance, e.g. a resistor or constant current generator, to form a longtailed pair (Fig. 2, not shown).
