Hybrid relays are changing the way we think about switching inside electronic circuits. By combining the fast response of solid-state components with the reliability of mechanical contacts, these devices offer the best of both worlds...
Hybrid relay basics: Why engineers are switching smarter
Circuit controls ratiometric or simultaneous power-up of multiple rails
Many applications use FPGAs, ASICs, or DSP chips, which usually require multiple voltage rails, typically two: the core voltage and the I/O voltage...
Power bank "Keep-alive"
A simple module to keep power banks from turning off, when your DIY circuit draws low currents...
Increasing bit resolution with oversampling
Many electronic designs contain an ADC, or more than one, to read various signals and voltages. Often, these ADCs are included as part of the microcontroller (MCU) being used...
Unusual 2N3904 transistor circuit
A Planet Analog article, “2N3904: Why use a 60-year-old transistor?” by Bill Schweber, inspired some interest in this old transistor and how it’s commonly used, and if any uncommon uses might exist...
Qorvo introduces TDD beamformer IC for compact, power-efficient Ku-band SATCOM terminals
Qorvo announced the release of a Ku-band beamformer IC designed to meet the growing demand for terminals that support time-division duplexing in compact and power-sensitive SATCOM applications...
PWM buck regulator interface generalized design equations
A while back, I published the Design Idea “Simple PWM interface can program regulators for VOUT < VSENSE”. It showed some simple circuits for PWM programming of standard bucking-type regulator chips...
