Abstract
A system for automatically controlling the gain-bandwidth product of operational amplifiers, wherein a gain-bandwidth product (G*B) of one of the amplifiers placed on the same chip as the amplifiers to be controlled is measured and the resulting signal is used to control through a bias circuit, the gain-bandwidth products of all the amplifiers, the value of these products being presettable by the frequeny of a control signal sent to the system input. The reference amplifier is highly compensated in the configuration of voltage follower.
