Bi-directional Logic Level Shifter


VGS (th) = 1.3 V (Threshold Voltage)
Input = 0V ; VGS > VGS(th) ; FET = ON ; Output = 0V
Input = 3.3V ; VGS < VGS(th) ; FET = OFF ; Output = 5V

A simulation of the above circuit can be seen in the YouTube video link.

Schmitt trigger for cleaning up noisy or slow-rising digital signals

  A Schmitt trigger is a circuit that converts an analog input signal into a digital output signal with hysteresis. It's characterised b...
