The Next-Generation Semiconductor for Power Electronics

Researchers have demonstrated the high-performance potential of an experimental transistor made of a semiconductor called beta gallium oxide, which could bring new ultra-efficient switches for applications such as the power grid, military ships and aircraft. The semiconductor is promising for next-generation “power electronics,” or devices needed to control the flow of electrical energy in circuits.

Inside the 74181 ALU chip: die photos and reverse engineering

What’s inside a TTL chip? To find out, I opened up a 74181 ALU chip, took high-resolution die photos, and reverse-engineered the chip.1 Inside I found several types of gates, implemented with interesting circuitry and unusual transistors. The 74181 was a popular chip in the 1970s used to perform calculations in the arithmetic-logic unit (ALU)

Redefining a new state-of-the-art in microampere current-sense amplifiers

Sensing and controlling supply current flow are a fundamental re- quirement in most all electronic systems from battery-operated, portable equipment to mobile or fixed-platform power manage- ment and dc motor control. High-side current-sense amplifiers (or “CSAs”) are useful in these applications especially where power consumption is an important design parameter. New CSA devel- opments offer

Radioactivity detection using very simple ionization chamber

Today I will show a very simple ionization chamber that can detect radioactivity. I was able to detect with it ionizing radiation from a smoke detector (Am241 isotope). It’s also immune to electromagnetic interference (EMI) due to a good shielding. This device doesn’t explicitly use any power supply. It’s connected to a multimeter set to
