circuit pair is connected to terminal 10 to receive the voltage of the cml logic gate voltage supply the collector of transistor 18 is connected to another resistor 21 and to the base of a further npn bipolar transistor 22 serving as the output stage of the amplifier thus the voltage occuring at the collector of transistor 18 provides the output signal of the input differential amplifier stage to operate output stage transistor 22 resistor 21 has a typical value of 746 u03c9 transistor 22 is connected as an emitter follower through having its emitter connected to reference generator output 12 and its collector connected to terminal 10 the emitter load for transistor 22 in the circuit disregarding the loads which may be connected to output 12 is another current sink formed by another npn bipolar transistor 23 and a further resistor 24 this output load current sink comprising these latter two circuit components again operates just as does the voltage translating circuit current sink components transistor 14 and resistor 15 but the value of resistor 24 is typically 750 u03c9 to again give a somewhat smaller sink current the connection of the end of resistor 21 opposite its connection.
