▪ Zener diode
A Zener diode is a silicon semiconductor device that permits current to flow in either a
forward or reverse direction. The diode consists of a special, heavily doped p-n junction,
designed to conduct in the reverse direction when a certain specified voltage is reached

▪ Clamper Circuit
Positive
A Clamper Circuit is a circuit
that adds a DC level to an AC
signal. Actually, the positive
and negative peaks of the
signals can be placed at
desired levels using the
clamping circuits. As the DC
level gets shifted, a clamper
circuit is called as a Level
Shifter

▪ Transistor
A transistor is a semiconductor device used to amplify or switch electronic signals and
electrical power. It is composed of semiconductor material usually with at least three
terminals for connection to an external circuit

▪ Transistor
Transistor switches can be used to switch a low voltage DC
device (e.g. LED’s) ON or OFF by using a transistor in its
saturated or cut-off stat
