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 ...
A previous design idea (DI), “Gated 555 astable hits the ground running” fixed the problem of the excessively long first pulse generated by 555 astables when gated by the RESET pin from ...
