Abstract :
New voltage-mode min/max circuits are introduced that have a simple architecture. Unlike conventional winner-take-all or source follower based schemes, the proposed circuits are characterised by reduced voltage swing at all internal nodes and by a very low output impedance, which enables them to provide high-speed and high-precision operation. Their complexity grows linearly with the number of inputs. The characterisation of a test chip prototype has provided experimental verification of these features
