Patent JP-S555559-A (JP)
Title: Integrated circuit
Inventor: SANO YOSHIAKI
IPC: H03F3/30
Filed: 1978-06-29
Abstract: PURPOSE:To simplify the constitution of BTL connection circuit by using the second amplifier taking the output of the first amplifier as inversion type negative feedback. CONSTITUTION:The negative feedback constant of the amplifier A1 is determined with the resistors R1, R2 and capacitor C1. The DC level of output is set to 1/2 of the power supply voltage Vcc. Accordingly, the output of the amplifier A1 is connected to the amplifier A4 via the inversion type negative feedback circuit consisting of the resistors R3' and R4', and bias of Vcc/c is given to the positive input, then the DC output level of the amplifier A4 is Vcc/2. With R3'=R4', the output of opposite phase can be obtained from the amplifiers A1 and A4. This output is taken as the same value and a load is connected between the output terminals. Further, by taking the output of the amplifier A1 as one input, the both gains can be adjusted with the adjustment of the resistor R1 only. The balance of the amplifiers can simply be taken with the resistors R3' and R4'.

IPC: H05B39/02
Filed: 1990-03-28
Abstract: PURPOSE:To prevent destruction of output part of a bipolar logical circuit by turning on an NPN transistor before the logical circuit is operated, and thereby relieving the rush current into the logical circuit. CONSTITUTION:When a high level signal is fed to an input terminal 1, an NPN transistor 6 is turned on before a bipolar logical circuit 4 is operated to actuate flowing of a dark current in such a degree as not lighting an incandescent lamp 5.
