A variety of analog front-end functions typically assist ADCs to do their jobs. These include instrumentation amplifiers, digitally programmable gain, and sample and holds. This circuit is a bit atypical in merging all three of these functions...
Negative time-constant and PWM program a versatile ADC front end
Pocket-size white noise generator for quickly testing circuit signal response. Part 1 - Noise discussion
Noise in electrical circuits is typically the enemy, and any self-respecting circuit should output as little noise as possible. Nevertheless, there are cases where a well-characterized source of noise with no other signal is entirely the desired output...
Phantom microphone power - the ghost in the machine
Modern day recording and broadcast is a mixed bag for today's audio engineers when it comes to input signal chains. Microphone electronic technology really hasn't changed that much over the last 50 years...
A fully analog electronic dice
An electronic dice is always an enjoyable project, which is easy to implement with some lines of program code on a microcontroller, or with a few digital components. However, implementing an electronic dice in analog technology is more of a challenge...
Half & Half piezo drive algorithm tames overshoot and ringing
Piezoelectric actuators are excellent fast and precise means for generation and control of micro, nano, and even atomic scale movement on millisecond and faster timescales. Unfortunately, they are also excellent high-Q resonators...
Simple circuit tests twisted-pair cables
Using the system shown, you can quickly test a cable containing twisted-wire pairs and detect open or reversed pairs, shorted pairs, and shorts between unrelated pairs...
Empower's new ultra-low 1 pH ESL silicon capacitor tightens voltage regulation for AI chips
Empower Semiconductor unveiled the largest silicon capacitor in its ECAP product family for high frequency decoupling...
Add noise measurements to your benchtop tools
The biggest problem with precision noise measurement is that the noise floor you’re trying to evaluate is frequently below the sensitivity of your measuring instruments. The dominant technique for gaging precision op-amp noise is to calculate it from your measurements...
Precise photovoltaic I-V characterization
Photovoltaic (PV) modules are popular and affordable sources of renewable energy. Most photovoltaic modules last about 20 years, but thermal stress and moisture ingress, among other causes, can degrade a module’s output power over time...
Remembering John B. Goodenough, inventor of the lithium-ion battery
Dr. Goodenough received a Nobel Prize at the age of 97 for his contributions to making the Lithium-ion battery a reality...
