Schmitt Trigger Inverters

Schmitt trigger inverters are a type of active circuit that convert an analog input signal to a digital output signal.

How do Schmitt trigger inverters work?

A Schmitt Trigger is a type of circuit which generates an output waveform (alternating current) to convert an analog input to a digital output signal.

Types of Schmitt trigger inverters

There are many integrated circuits (ICs) that have built-in Schmitt Triggers on their inputs. They can also be built using a type of transistor or by using an operational amplifier (an amplifier with a high input) or comparator.

Operational amplifier

An operational amplifier is an electronic amplifier with an inverting input that is connected to a voltage so that the circuit can convert signal successfully.

Non-symmetrical Schmitt trigger

A non-symmetrical Schmitt trigger is a type of circuit used to invert a Schmitt trigger in order to achieve two different non-symmetrical thresholds. These help to convert analog signal into digital.
