Apparatus and methods for calibrating analog circuitry in an integrated circuit

摘要

The present disclosure provides apparatus and methods for the calibration of analog circuitry (104) on an integrated circuit (100). One embodiment relates to a method of calibrating analog circuitry (104) within an integrated circuit (100). A microcontroller (110) that is embedded in the integrated circuit (100) is booted up. A reset control signal is sent to reset an analog circuit (104) in the integrated circuit (100), and a response signal for the analog circuit (104) is monitored by the microcontroller (110). Based on the response signal, a calibration parameter for the analog circuit (104) is determined, and the analog circuit (104) is configured using the calibration parameter. Other embodiments, aspects and features are also disclosed.
