Title: Amplifier circuit
Inventor: INUZUKA TERUO
IPC: H03F3/68
Filed: 1990-06-29
Abstract: PURPOSE:To obtain an amplifier circuit with driving capacity on which the driving capacity of an individual amplifier is added by connecting the input of the amplifier circuit comprised of plural operational amplifiers to which the same feedback is applied mutually, connecting the output mutually via resistors, and taking out an output terminal from the intermediate point of those resistors. CONSTITUTION:The operational amplifiers OP1, OP2 to which full feedback is applied comprise a voltage-follower. The input are connected mutually, and are connected to an input terminal IN1. The output are connected to the output terminal VO1 via the resistors R1, R2. Since the operational amplifiers OP1, OP2 are provided with input offset voltages actually, potential difference equivalent to the difference of the input offset voltages is generated as the output of the operational amplifiers OP1, OP2. The output resistance of the operational amplifiers OP1, OP2 are low in an ordinary state, and also the full feedback is applied to them, therefore, the output resistance goes down further by the function of the feedback. By inserting the resistors R1, R2 to an output circuit, only a current DELTAVI0/(R1+R2) flows between the operational amplifiers OP1 and OP2 for the input offset voltage difference DELTAVI0 of the operational amplifiers OP1, OP2.
