What is the output voltage Vo for the circuit below for Vi = Vm sinωt
What is the output voltage Vo for the circuit below for Vi = Vm sinωt
Right Answer is:
2Vm
SOLUTION
A positive clamper circuit is an electronic circuit designed to shift the entire waveform of an input signal upward, ensuring that the output voltage remains above a specified reference level, typically zero volts. This circuit is particularly useful in applications where it is necessary to prevent negative voltages from appearing at the output.
Positive peak detector circuit: This circuit detects the positive peak value of the input signal and provides it in the output.
This diagram can be broken out into two circuits:
- Positive clamper circuit
- Positive peak detector circuit
Vo = 2Vi
Vo = 2(Vm sinωt)
The peak value of output voltage is:
Vo = 2Vm
