In this Design Idea (DI), the classic Schmitt-trigger-based RC oscillator is “hacked” and analyzed using the simulation software QSPICE. You might reasonably ask why one would do this, given that ...

A typical voltage-to-frequencyconverter—also known as aVCO (voltage-controlled oscillator)—IC has a simple linear tuning characteristicrelating input voltage to outputfrequency. It is usually of the ...

There are a few AVR microcontrollers with onboard temperature sensors. These temperature sensors are neither accurate nor precise, but they do work for a few use cases. [Thomas] came up with a little ...

Voltage-controlled oscillator-based analog-to-digital converters (VCO-based ADCs) represent an emerging class of digitisation circuits that harness the frequency-modulating properties of VCOs to ...
