Title: Differential amplifier circuit
Inventor: FUJITANI KENJI
IPC: H03F3/45
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a differential amplifier circuit which can stably operate, regardless of the fluctuations in ground potential by connecting the gate of a transistor used for a constant current source to the common connection point of gates of a current mirror circuit. SOLUTION: If a ground potential GND rises higher than the original potential 0, the gate potential VG of a transistor TR Q5A lowers by a degree equivalent to the rise in the GND. Then the potential rises at a node B of a differential circuit 1 by the lowering of the VG. Furthermore, the rise in the potential of the node B lowers the gate potentials of TR Q1 and Q2. As a result, the current capability of both the TR Q1 and Q2 are deteriorated similar to the TR Q5A. Finally, the rise in potential at a node A is reached. Thus, the rise in the GND is reflected as the rise of the gate control voltage of the TR Q5A. Then the current capability of the TR Q5A is recovered, to prevent the deterioration of its performance that is caused by the rise in the GND.
