i have designed a RC osc circuit, and using a bandgap to generate the reference current and reference voltage of the osc, when simulating the bandgap only, the start up time is 1ms orso; but when i simulate the bandgap and osc together, the bandgap's start-up becomes very slow, about 10ms to settle, why? the loading is the same for the two case, what caused the slow start-up of bandgap? pls help me, thanks.
