A current sensor with PWM output is a very useful type of device. Traditionally, the device can serve in a digital application where the host microcontroller can determine the ratio of the on-time to ...

Several microcontroller applications utilize a digital-to-analog converter. Though many of these applications require a complex DAC, some may only need a simple single-channel DAC. Because most MCUs ...

This article describes a simple technique for using a processors PWM output to produce an analog control voltage that matches the load’s input range, thus maximizing control resolution. Most ...

What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...

Level-crossing analog-to-digital converters (LC-ADCs) represent an innovative approach to signal digitisation that departs from conventional uniform sampling. Instead of capturing signals at fixed ...

Cypress's Dave Van Ess proposes a novel way of analyzing mixed-signal circuits in terms of serializing the digitized analog signal and then assesing the relative time the signal is high. As an “old ...
