For battery-powered circuits, it is easy to build an ultralow-current crystal oscillator designed around a 32.768-kHz crystal. This crystal is common for real-time-clock circuits. Because these ...

How do you test the oscillator circuit you just made that runs between 200MHz and 380MHz if all you have is a 100MHz oscilloscope, a few multimeters and a DC power supply? One answer is to put away ...

This application note presents the need to use an external Pierce oscillator to replace the RTC oscillator circuit that makes EP93xx susceptible to on-chip noises. It describes the implementation of ...

A few months ago we brought you some experiments from [Bill Meara, N2CQR], in which he investigated the use of a glue stick as the former for a permeability tuned inductor. His set-up was very much in ...

The evolution of precision clocks. The tradeoffs between MEMS vs. crystal oscillators. The manufacture and cost issues involved. Almost every electronic device you can imagine depends on a precision ...

Just as most electronic products today contain at least one embedded controller, most also have at least one crystal oscillator. In fact, some multiprotocol networking and telecom equipment can ...

Houseplants rarely die suddenly. Check out this clever plant humidity monitor circuit that Elektor presented in the summer of ...

Elektor introduced a clever seat belt reminder circuit built with simple logic to trigger a flashing warning light.
