Patent JP-S6066518-A (JP)
Title: Semiconductor integrated circuit
Inventor: SATOU HISAYASU
IPC: H01L27/06
Filed: 1983-09-21
Abstract: PURPOSE:To attain an output voltage and noise sensitivity which are stable to variance of a power source voltage, by providing resistances having constant current characteristics between the emitter common connection point of a differential pair of transistors TR and a negative power supply terminal and between the base of the second TR and the negative power supply terminal. CONSTITUTION:When currents flowed to resistors Rp1 and Rp2 having constant current characteristics are denoted as Ip1 and Ip2 respectively, output voltage VOH and VOL (based on an earth voltage VCC) appearing in an output terminal O approximate -VBE(Q3) and -VBE(Q3)-Ip1R2 respectively. A reference voltage VBB approximates -VBE(Q4)-Ip2R5. VBE(Q4) and VBE(Q3) are voltages between bases and emitters of TRs Q4 and Q3 respectively. Since currents Ip1 and Ip2 are not affected by variance of the power source voltage because of constant current characteristics when voltages applied to resistors Rp1 and Rp2 are higher than a voltage VA, the output voltage VOL and the reference voltage VBB are constant independently of variance of the power source voltage. The noise sensitivity is always constant.
