Bias ON
1. Disable the output of the PPG
2. Set Vdd=0V Vctrl1=0V Vctrl2=0 Vg1=0V
3. Set Vg1=-1.5V Vg2=-1.5V
4. Increase Vdd to 5V observing Idd.
5. Set Vctrl2=+0.2V
6. Make Vg1 more positive until Idd=65mA.
7. Make Vg2 more positive until Idd=180 – 220 mA.
8. Enable the output of the PPG.
9. Output Swing Adjust: Adjust Vctrl2 slightly positive to increase output swing or adjust
Vctrl slightly negative to decrease the output swing.
10. Crossover Adjust: Adjust Vg2 slightly positive to push the crossover down or adjust
Vg2 slightly negative to push the crossover up.
Demonstration Board - Bias ON/OFF Procedure
and Vg2=0V
- Assure Idd=0mA
- Idd should still be 0mA
- This is Id1 (current into the first stage)
- Typical value for
- This sets Id2T to 115 -155 mA.
- This sets Id2T to 115 -155 mA.
- Typical value for Vg2 is -0.55V
- Set Vin=500mV
- Typical value for
- Typical value for
crossover with Vo=6V.
Vo=6V.
