In 1938, the Journal of Scientific Instruments published details of a comparator circuit that converted a slowly varying input signal into an abrupt change in output voltage. Based on cross-coupled ...

Looks like another shot has been fired in the simmering Coil Gun Control War. This time, [Great Scott] is taken to the discrete woodshed with a simplified and improved control circuit using a single ...

In this Design Idea, we look at how electromechanical relays display hysteresis behavior that is surprisingly similar to the solid-state Schmitt trigger circuits, and how they can be used for many ...

The circuit in Figure 1 is a single-supply version of a programmable Schmitt trigger, or a comparator with hysteresis. A comparator, A1, and a digitally programmable potentiometer (DPP1) are used for ...

D-type flip-flops, with the invertedoutput connected to theD input, can toggle a clock signal. Ifyour circuit has an extra Schmitt-triggerinverter gate, you can use it to accomplishthe same thing.

In biomedical instrumentation (for example), we're sometimes faced with very noisy or badly-behaved signals from which we need to derive information. In this example, I needed to “square up” a ...

Now-a-days, electronic devices are portable which requires low power/low voltage requirement to maximize the battery lifetime. The authors propose Schmitt Trigger based SRAM bitcell that can operate ...
