1. A circuit for peak voltage detection, comprising:
a diode-based peak detector having a first diode, the diode-based peak detector configured to receive a signal for peak voltage detection and generate a first voltage of a stable level indicative of a peak voltage of the signal based on the first diode; and a compensation circuit having a second diode, the compensation circuit configured to receive the first voltage and generate a second voltage of a stable level that is independent of the first diode, the second diode configured to match the first diode, and the second diode being coupled with more than two resistors, a first resistor being coupled in series with a second resistor, the first resistor and the second resistor together coupled in parallel with a capacitor, the first resistor, the second resistor, and the capacitor together coupled in series with the first diode, a third resistor coupled between the first resistor and the second resistor, and a fourth resistor coupled in series with the third resistor. |
