Fully-Differential (FD) circuits are unavoidable under low voltage power supply conditions. To properly operate FD circuits the use of common-mode feedback is compulsory. The conceptual approach to implement the common-mode feedback circuits is introduced. Furthermore, the use of common-mode feedforward techniques to enhance the common-mode rejection ratio is introduced. It is demonstrated that...

This paper outlines a dynamic theory of development and adaptation in neural networks with feedback connections. Given input ensemble, the connections change in strength according to an associative learning rule and approach a stable state where the neuronal outputs are decorrelated. We apply this theory to primary visual cortex and examine the implications of the dynamical decorrelation of the...

The feasibility of automatically controlling water levels and deliveries on the Salt River Project SRP canal system through computer-based algorithms is being investigated. The proposed control system automates and enhances functions already performed by SRP operators, namely feedforward routing of scheduled demand changes, feedback control of downstream water levels, and flow control at check ...
