TPS23755: Test Bode plot on TPS23755

Part Number: TPS23755

Dear Sir 

If I want to test phase margin & gain Margin on TPS23755, where can I add the test signal?

Is it correct to add to R14? And which single level should I add? -27dBm?

Allen

  • Hi Allen,

    Yes the AC small signal should be injected across R14. For the amplitude, I recommend making sure the signal is smallenough such that the AC
    signal can be recognized. -27dbm (~30mV) should be okay.
