DC BIAS EVALUATION IN AN AC COUPLED CIRCUIT VIA TRANSIENT GAIN RESPONSE |
摘要 |
A method and system are provided for the monitoring of direct current bias, the system including switching an amplifier of known scale factor from low to high; monitoring a step change in bias generated by the gain change; measuring, the response to the bias change via appropriate peak detection logic; and determining the amount of bias present at an input based on AC response and the amplifier scale factor.
