Abstract
The present disclosure provides apparatus and methods for the calibration of analog circuitry on an integrated circuit. One embodiment relates to a method of calibrating analog circuitry within an integrated circuit. A microcontroller that is embedded in the integrated circuit is booted up. A reset control signal is sent to reset an analog circuit in the integrated circuit, and a response signal for the analog circuit is monitored by the microcontroller. Based on the response signal, a calibration parameter for the analog circuit is determined, and the analog circuit isconfigured using the calibration parameter. Other embodiments, aspects and features are also disclosed.
