Adding the long-first-pulse malady in less traditional 555 astable topologies including CMOS- and bipolar-based oscillators that generate 50:50 symmetrical square waves. Figure 1 The problem—the first ...

In the classic configuration and most variants of the astable 555 multivibrator circuit, the timing characteristics are based on the charging and discharging of a capacitor. However, it can be argued ...

We’ve probably all given a lot of thought to breathing this year in various contexts. Though breathing is something we all must do, this simple act has become quite the troublemaker in 2020. They say ...
