Low Power Precision Current Distribution Network

چکیده
This paper presents a method for creating and distributing small, precision currents throughout an integrated circuit. The system is designed for use in a bionic cochlear implant. A bandgap reference and an off-chip precision resistor create a single precision reference current. This current is then converted into an oscillation frequency. This oscillation frequency is distributed losslessly around the chip, and is converted back to current where it is needed. By clocking down the frequency of oscillation, the magnitude of the current can be varied by several orders of magnitude.

متن کاملDistributed Generation Effects on Unbalanced Distribution Network Losses Considering Cost and Security Indices
Due to the increasing interest on renewable sources in recent years, the studies on integration of distributed generation to the power grid have rapidly increased. In order to minimize line losses of power systems, it is crucially important to define the size and location of local generation to be placed. Minimizing the losses in the system would bring two types of saving, in real life, one is ...
