Q. A silicon diode has a threshold voltage of $0.7 \,V$. If an input voltage given by $2 \sin (\pi t)$ is supplied to a half wave rectifier circuit using this diode, the rectified output has a peak value of

Semiconductor Electronics: Materials Devices and Simple Circuits

Solution:

Peak value of rectified output voltage
= peak value of input voltage - barrier voltage
$=2-0.7=1.3\, V$
