Title: Logical circuit
Inventor: SAKURAI TAKAYASU
IPC: H03K19/096
Filed: 1982-05-04
Abstract: PURPOSE:To attain the high-circuit integration without increasing the power consumption of a circuit, by giving a delay to a precharge start time of a logical gate of the post-stage by a prescribed time or over from the precharge start time of the logical gates at the pre-stage. CONSTITUTION:Gates 100, 102 and 104 of logical gates 100-104 are output negative logical gates and the gates 101, 103 are output positive logical gates. The delay in a precharge signal inversion phip' is generated at inverter trains 105-109. Since the signal inversion phip' is delayed at the inverter trains, inputs 202, 203, 214 of the gate 102 are a level to turn off the logical switch included in the gate 102 and the precharge is started after the gate 102 is turned off. Thus, when a precharge transistor (TR) T102 is turned on, the gate 102 is turned off and no DC path is produced. Thus, no TR is required to cross the DC path and the area of the TR group forming the logical blocks is reduced.

Abstract: PURPOSE:To eliminate a current error caused by the difference of a voltage between the base and collector of a cascode transistor circuit and to reduce off-set and the drift of a temperature by integrating a current mirror circuit and a current source into a gain stage part. CONSTITUTION:A second current mirror circuit 13 is operated to make a collector/base voltage VCB same for transistors Q11 and Q12 of the cascode transistor circuit. In the second current mirror circuit 13, since the emitter of a transistor Q16 is grounded, a potential for the emitter of a transistor Q17 is also made equal to a ground potential (0V). As a result, the collector of the transistor Q11 goes to be the ground potential as well and when an output OUT is 0V, the VCB of the transistors Q11 and Q12 is made equal. Accordingly, at such a time, the VCB of the transistors Q11 and Q12 in a cascode transistor circuit 11 is made equal and the current error is eliminated.
