Abstract

A fast start up oscillator. The fast start-up oscillator includes a power-on-reset detect circuit, a bandgap circuit, a voltage detect circuit, a RC-oscillator, and a count two circuit. The fast start-up oscillator is provided with a fast stabilized voltage source to ensure oscillation accurate and quickly such that the system is woken up.
