Self-Programming Hybrid Memristor/Transistor Circuit Could Continue Moore's Law

March 2, 2009 10:48 am | Comments

In a recent study, a team of researchers from Hewlett-Packard Laboratories in Palo Alto, California, have fabricated and demonstrated a hybrid memristor/transistor circuit for the first time. The team demonstrated conditional programming of a nanomemristor by the hybrid circuit, showing that the same elements in a circuit can be configured to act as logic, signal routing, and memory.

One-Volt Oscillators Provide Low Current Consumption Across Full Frequency Range

March 2, 2009 10:47 am | Comments

Fox Electronics' 1-V F200 Series oscillators come in a 2.5 mm × 2.0 mm package and feature a standby function that reduces the oscillator's current consumption to 5 µA for efficient power use. The F200's low current draw of 2.5 mA across the 1.8 MHz to 32 MHz frequency range and 3.5 mA from 32.1 MHz to 50.0 MHz makes the oscillator series appropriate for
