Patent JP-S60260224-A (JP)
Title: Semiconductor logical circuit
Inventor: TANAKA SHIYOUICHI
IPC: H03K19/003
Filed: 1984-06-06
Abstract: PURPOSE:To improve the power consumption of an unsaturated logical circuit and noise margin by connecting the output contact of a junction control type amplifier element and a main power supply, and connecting a rectifier element in parallel with the point. CONSTITUTION:A collector of a transistor (Tr) 2 is connected to a high potential power supply VD via a load 4 and a Tr 7 having a prescribed conduction voltage VR with diode connection is connected in parallel with the load 4. Emitters of Trs 1, 2 are connected in common and a low potential power supply VS is connected from the connecting point via a load 3. Since the level of a collector 12 being the output contact of the Tr 2 is not decreased by a prescribed potential VD-VR or over, the Tr 2 is activated at high speed at the unsaturation mode. When an input voltage fed to the base A exceeds a threshold voltage VT, the voltage at an output point 12 is lowered rapidly. As a result, noise margin is increased. Since the low voltage operation is attained, the power consumption is reduced and the degree of integration is improved.
