What is the time constant? In a 555 timer circuit, the time period for which the output remains high or low is influenced by two key components: capacitance (C) and resistance (R).

The shorter time constant required of the “Soft Reset” one-shot alleviates the demand on the higher value resistor and capacitor but not on the capacitor type. The X7R type dielectric is the right ...

Instead of using a monolithic DPGA, you can use two op amps and three analog switches to build a DPGA employing negative time constants. You’re no doubt familiar with the e –t/RC convergent ...
