How can you count bits in hardware? In this article, I reverse-engineer the circuit used by the ARM1 processor to count the number of set bits in a 16-bit field, showing how individual transistors form multiplexers, which are combined into adders, and finally form the bit counter. The ARM1 is the ancestor of the processor …

Let’s see the video first. In todayās society, more and more attention to the quality of life, pursue the healthy and comfortable living environment. So we made this device to monitor the indoor temperature and humidity, when the humidity falls below the safe values, it will automatically open the humidifier. Step 1: What You Need …
For the first time in 60 years, a new higher-performance semiconductor technology is less expensive to produce than the silicon counterpart. Gallium nitride (GaN), has demonstrated both a dramatic improvement in transistor performance and the ability to be produced at a lower cost than silicon. GaN transistors have unleashed new applications as a result of …
Summary The MCP6V01 auto-zeroed op-amp features an ultra low offset voltage (VOS) and high common mode rejection ratio (CMRR), which makes it applicable to temperature measurement. The MCP6V01 thermocouple auto-zeroed reference design demonstrates how to measure electromotive force (EMF) voltage at the cold junction of the thermocouple in order to accurately measure temperature at the …
In the world of electronic components, there are many devices out there that do their job well and reliably, but are almost never heard of ā even though they may be vital to equipment that plays a role in our technology-driven lives. The radio frequency (RF) circulator is just such a device: it has simply …

Description The DS3231 is a low-cost, extremely accurate IĀ²C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains accurate timekeeping when main power to the device is interrupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as …
Plessey Semiconductors today announced the release of the PS2292X family of low dropout linear regulators for point of load applications. The devices are part of a high current, single supply LDO family that operates from an input voltage as low as 1.7V. Targeted for industrial, medical, communication, computing and consumer markets, the regulators are an …
