1sRC
1sRC is a colloquial term used to describe a one-shot timing circuit based on a resistor–capacitor (RC) network. In practice, 1sRC refers to a monostable circuit whose output pulse duration is set by the RC time constant and is typically around one second, though exact timing depends on component values and circuit design.
Operation of a 1sRC circuit typically follows a trigger event. The triggering action drives the RC network
Common implementations include:
- Discrete transistor-based monostable circuits using an RC network to shape the pulse.
- A 555 timer configured in monostable (one-shot) mode, with the RC network setting the pulse width.
- Digital or mixed-signal designs that employ a Schmitt trigger or buffer in conjunction with an RC
Design considerations for 1sRC circuits include tolerances of resistors and capacitors (which affect burst width), temperature
Applications of 1sRC circuits include switch debouncing, pulse stretching, simple timing delays in control systems, and
