Abstract

Integrated circuits (IC) that provide an integrated voltage follower or voltage-to-current conversion are common. Precise voltage followers are usually based on operational amplifier structures which require frequency compensation. Such compensation circuitry consumes a great deal of die space and thus requires large die size. In contrast, simple voltage followers occupy very small die size, however their precision and linearity is poor. Therefore, it would be desirable to devise a new circuit having high precision and low die size.
