  • Multi-input differential circuit
    Publication number: 20050017761
    Abstract: The invention provides a NANO-ampere operable differential circuit by means of a few additional components. The multi-input differential circuit consists of more than three input elements that are connected to the same tail node, and an adaptive bias current control circuit. Applications of this multi-input differential circuit, which are, for instance comparators and voltage followers, do have a very low operation current at a normal operation mode. The proposed differential circuit is applicable for all kinds of analog complex circuits to attain nano-power operation.
    Type: Application
