Abstract

1446796 Automatic voltage regulation MOTOROLA Inc 11 Oct 1974 [20 Dec 1973] 44241/74 Heading G3X A regulated voltage source for ECL logic circuits includes a transistor circuit supplying a voltage with a predetermined positive temperature coefficient to the base of a shunt regulator transistor connected to an output transistor. The collector of the shunt transistor is connected to a circuit for compensating variations in the base-emitter voltage of the transistor which occur when the source input voltage varies. As shown in Fig. 2, the value of a resistor R2 and the junction areas of transistors T1, T2 are chosen so that the currents I1, I2 in each transistor are equal and a temperature dependent voltage related to the difference in base-emitter voltage 5 of the transistors is produced at the collector of transistor T2. The currents I1, I2 are input voltage independent due to the circuit inter-connections, and a regulated voltage V1 is therefore produced across a transistor T4 relative to the earth line 10. A second output voltage V2, relative to input line 11, is also made independent of input voltage by including in the circuit diode-connected transistors T7, T8 which compensate for variations in the baseemitter voltage of transistor 76 which acts as a shunt regulator. In another embodiment, Fig. 3 (not shown) transistor T7 is replaced by a further transistor (T9) connected between the bases of transistors T6 and T3. A further embodiment, Fig. 4 (not shown), uses an additional shunt transistor (T10) to compensate for variations in the voltage of transistor T6. Resistors (R9, R10) may be included to convert the circuit from a zero temperature coefficient supply to one with a desired coefficient complementary to that of the circuit to which the output voltage is to be supplied.
