Research and Design of Watchdog circuit on LTE-A Mobile phone |
| |
| Abstract: | System program of Long Term Evolution Advanced(LTE-A) mobile phone is failure, which can recover by pulling out battery. Watchdog circuit scheme based on discrete device is proposed, accompanying with software control of Baseband processor General Purpose Input Output (GPIO), and reset time of watchdog circuit can be satisfied for system program reboot. Then system test are performed. |
