A proportional-integral-derivative (PID) analog controller and a method for testing a PID analog controller of a DC/DC converter

摘要

Embodiments of a method for testing a Proportional-Integral-Derivative (PID) analog controller of a Direct Current (DC)/DC converter and a PID analog controller of a DC/DC converter are described. In one embodiment, a method for testing a PID analog controller of a DC/DC converter involves setting an analog regulation loop, which is formed by an operational transconductance amplifier (OTA) of the PID analog controller and a feedback network of the PID analog controller, to a stable condition and testing a DC parameter of the PID analog controller and setting the analog regulation loop to an unstable condition and testing an Alternate Current (AC) parameter of the PID analog controller. Other embodiments are also described.
