555 square wave generator

Square wave generators are generally used in electronics and in signal processing . It is just like a Schmitt trigger circuit in which the reference voltage for the comparator depends on the output voltage. It is also said to be an astable multivibrator. A square-wave generator obviously produces a square wave.16 Ara 2020

The square signal is able to generate around 19% more force than the sinusoidal signal . As the frequency increase, the difference in forces starts decreasing until the frequency in which the DEP force of square signal is equal to the DEP force of sinusoidal signal.

Square waves are typically generated by metal–oxide–semiconductor field-effect transistor (MOSFET) devices due to their rapid on–off electronic switching behavior, in contrast to BJT transistors which slowly generate signals more closely resembling sine waves rather than square waves.
