A Carbon Nanotube Microprocessor Mature Enough to Say Hello
https://www.electronics-lab.com/carbon-nanotube-microprocessor-mature-enough-say-hello/
Did you know that researchers are looking for an alternative to silicon? Did you know in principle that Carbon Nanotubes processor could run three times faster while consuming about one-third of the energy of their silicon predecessor? The Engineers at MIT and Analog Devices have created the first fully programmable 16-bit Carbon Nanotube microprocessor. Since […]
Torex launches positive voltage LDO regulators based on CMOS
https://www.electronics-lab.com/torex-launches-positive-voltage-ldo-regulators-based-cmos/
The XD6506 is a series of voltage regulators from Torex Semiconductor that is manufactured using CMOS processes. The positive voltage LDO regulators are qualified to AEC-Q100 Grade 2. The regulators achieve low supply current, 0.8 microA (typical) and consist of a reference voltage source, an error amplifier, a current fold-back circuit, and a phase compensation […]
CMOS-TTL QUADRATURE ENCODER USING LS7084
https://www.electronics-lab.com/cmos-ttl-quadrature-encoder-using-ls7084/
The quadrature LS7084 Module is a CMOS quadrature clock converter. Quadrature clocks derived from optical or magnetic encoders, when applied to the A and B inputs of the LS7084 are converted to strings of a Clock and an Up/down direction control. These outputs can be interfaced directly with standard Up/Down counters for direction and position […]
The Making of a Cooled CMOS Camera
https://www.electronics-lab.com/making-cooled-cmos-camera/
landingfield.wordpress.com shows us their progress on how to make a cooled CMOS camera able to be used for astrophotography. In the last post, I uncovered a bug in the Vivado implementation which accidently removes the DIFF_TERM from my input buffer. With that problem solved, I picked up the project again with a goal to achieve […]
The smallest camera module for mobile devices
https://www.electronics-lab.com/smallest-camera-module-mobile-devices/
Nidec Copal, the world’s biggest manufacturer of camera shutters, has developed the smallest, thinnest and lightest camera module for mobile devices. It measures just 8.5 x 8.5 x 4.2 mm and weighs 0.57 g. The new camera module is about half the size of Nidec Copal’s previous module. by Harry Baggen @ elektormagazine.com The new camera module has a 16 megapixel, 1/3.1″ […]
Reverse engineering the popular 555 timer chip (CMOS version)
https://www.electronics-lab.com/reverse-engineering-popular-555-timer-chip-cmos-version/
Ken Shirriff reverse engineer the CMOS version of 555 timer IC and explains how it works. This article explains how the LMC555 timer chip works, from the tiny transistors and resistors on the silicon chip, to the functional units such as comparators and current mirrors that make it work. The popular 555 timer integrated circuit […]
Unipolar Stepper Motor Driver Circuit
https://www.electronics-lab.com/unipolar-stepper-motor-driver-circuit/
This unipolar stepper motor driver circuit is used to drive a 12V unipolar stepper motor with a current rating of 1.25A. It uses PCA9537 IC, which is a 10-pin CMOS device that provides 4 bits of General Purpose I/O (GPIO) expansion with interrupt and reset for I2C-bus/SMBus applications. It consists of a 4-bit configuration register […]
Tutorial on the Theory, Design and Characterization of a CMOS Transimpedance Amplifier
https://www.electronics-lab.com/tutorial-on-the-theory-design-and-characterization-of-a-cmos-transimpedance-amplifier/
In this episode, Shahriar and Shayan discuss the design and characterization of a deceptively simple CMOS inverter-based transimpedance amplifier. The the large and small signal behavior of the CMOS inverter is discussed and measured using the Keithley 2450 and 2460 source meters. The transient response is also measured using a Keysight MSO-S series oscilloscope. The […]
iCoupler – Digital Signal Isolator
https://www.electronics-lab.com/icoupler-digital-signal-isolator/
Clemens Valens @ elektormagazine.com discuss about the new iCoupler family of isolators from Analog Devices: Digital isolators based on transformers and capacitors use magnetic and electric fields to couple data across isolation barriers where optocouplers use light. Digital isolators can be manufactured using CMOS technology allowing the integration of signal conditioning circuitry in the chip […]
