100Vin, 5W out regulator uses primary-side control
https://www.electronics-lab.com/100vin-5w-regulator-uses-primary-side-control/
LT8303 is a monolithic flyback regulator in a TSOT-23 package that simplifies the design of isolated DC/DC converters. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no opto-isolator, LT1431 or third winding for regulation. by Graham Prophet @ edn-europe.com The LT8303 operates over a 5.5V to 100V input […]
Low noise Mini Electret Microphone PreAmplifier
https://www.electronics-lab.com/low-noise-mini-electret-microphone-preamplifier/
The single supply microphone pre-amplifier amplifies the output signal of an electret capsule microphone to audio line levels. An op amp is used as a trans-impedance amplifier to convert the output current from the microphone in to a signal level voltage. The circuit works with 9V so it is good choice for battery operated systems. […]

Printable battery paves the way for custom-shape power sources
https://www.electronics-lab.com/printable-battery-paves-way-custom-shape-power-sources/
A new type of batteries called “Printable Solid-State (PRISS) Lithium-Ion Batteries” was designed by a group of researchers from the Ulsan National Institute of Science and Technology (UNIST, South Korea). The new battery is created from consecutive layers of printed composite materials. With a simple stencil printing process followed by ultraviolet cross-linking, a solid-state composite […]

Temperature-to-period circuit provides linearization of thermistor response
https://www.electronics-lab.com/temperature-period-circuit-provides-linearization-thermistor-response/
by S Kaliyugavaradan, Anna University, Madras Institute of Technology, Chennai, India; Edited by Brad Thompson and Fran Granville -November 10, 2005 Designers often use thermistors rather than other temperature sensors because thermistors offer high sensitivity, compactness, low cost, and small time constants. But most thermistors’ resistance-versus-temperature characteristics are highly nonlinear and need correction for applications […]
