Title: Operational amplifier
Inventor: OKAMOTO TOSHIYUKI
IPC: H03F3/45
Filed: 1990-03-26
Abstract: PURPOSE:To obtain a high gain without being affected by a load transistor by forming the first step of an operational amplifier with two constant power sources, four input differential FET and four load FET or the like. CONSTITUTION:The first step of the operational amplifier is formed with P type differential FET M1-M2, which sources are connected to constant current sources I1 and I2, and N type FET M5-M8 for load. When the potential of an uninverted input terminal IN<+> is made higher than that of an inverted input terminal IN<->, a current to flow to the FET M1-M4 is reduced rather than that of the FET M2-M3 and the common gate potential of the FET M6 and M8 is increased. Then, the drain potential of the FET M8 is made low and the potential of the terminal IN is made high. Such a state is similar even when the potential of the terminal IN<+> is made high, and thus, the gain G1 of the first step is set under the condition of G1 G1 2XgmlXrd3. Thus, the gain of the operational amplifier is made high without being affected by a load TR in the first step. In the above mentioned expression, the gml is the mutual conductance of the FET M1 and the rd3 is the drain resistance of the FET M3.
