This document discusses different types of rectifier circuits including half-wave, full-wave, and peak detector rectifier circuits. It explains that half-wave rectifiers cause ripple due to the capacitor discharging each period and discusses ways to reduce ripple such as not allowing the capacitor to discharge as frequently. It also discusses the operation of full-wave and peak detector rectifier circuits.

Circuit

3. Tin
Half-Wave Rectifier
Cause of ripple: the capacitor is discharged for almost an entire period.

4. inversion
Ripple Reduction: Do not allow the capacitor to discharge so frequently

5. If Vin >0, D1 and D2 are off.
If Vin <0, D1 and D2 are on and
Vout>0.

6. If Vin >0, D1 and D2 are on,
Vout>0.
If Vin <0, D1 and D2 are off.

9. Vout=-Vin-2VD, on Vout=Vin-2VD, on

10. |Vin|<2VD,on

12. Modification:
1.Turn-on voltage
2.1/2 to account for inversion of negative
peaks.

13. VB=VD,on
VA=VP
VAB=VP-VD,on
Maximum reverse voltage is approximately Vp
Vp is the amplitude of Vin

14. A reverse diode voltage
must sustain larger reverse bias voltage

18. Limit the signal amplitude at a suitable point in the receiver

22. Electronic systems typically provide a global supply
voltage: 3V
Design of some circuits will be simplified if they from
a higher supply voltage.

23. Floating Capacitor Capacitor Divider

24. Ideal diode.
Vout pinned to 0 V
Positive charges begin to leave the left
Plate of C1, turning D1 off.
C1 is now a floating capacitor

27. Peak Detector0 to 2Vp waveform

28. Application:
We may need to shift the average level of a signal up
and down because the subsequent stage (e.g. an amplifier)
may not operate properly with the present dc level.

31. CK is 1: I1=1, diodes are shorted, and
Vin=Vout.
CK is 0,diodes are off, charges are stored
across C1.
