On the design of very small transconductance OTAs with reduced input offset
In this paper it will be demonstrated, from the theory and measurements, that series-parallel (SP) mirrors allow building current copiers with copy factors of thousands, without d...

Approximating the Bandwidth of Caterpillars
A caterpillar is a tree in which all vertices of degree three or more lie on one path, called the backbone. We present a polynomial time algorithm that produces a linear arrangeme...

The Tree Inclusion Problem: In Optimal Space and Faster
Given two rooted, ordered, and labeled trees P and T the tree inclusion problem is to determine if P can be obtained from T by deleting nodes in T. This problem has recently been r...

Evolving Modular Fast-Weight Networks for Control
Abstract. In practice, almost all control systems in use today implement some form of linear control. However, there are many tasks for which conventional control engineering metho...
