IPC: H03G3/10
Filed: 1987-05-07
Abstract: PURPOSE:To obtain a control circuit by adopting the constitution such that 1st and 2nd output voltages subjected to gain control respectively are obtained as differential outputs at 1st and 2nd differential amplifier output terminals by a control voltage as a differential output while no limit is imposed on the control signal. CONSTITUTION:The change in a control voltage V3 fed to a control terminal 4 is converted into a 1st control voltage V1 by a conversion circuit 5 and outputted to a 1st control voltage output terminal 6. Since the relation of I1=I4 exists in the constant current sources I1, I4, the difference between 1st and 2nd control voltages V1, V2 is nearly zero with the relation of equation V3-E2<<-R7.I1 and the gain is minimized. On the other hand, in the case of the relation of V3-E2>>R7.I1, the difference between the voltages V1, V2 is 4h {h=kT/q (k: Boltzmann's constant, T: absolute temperature, q: electric change of an electron)} or the value larger than it. Even when a control voltage V3 takes any value between a collector power terminal voltage VCC and ground, V2>V1 does not exist. Thus, the level of the control voltage V3 is selected freely.
