Abstract
A rapid start-up voltage reference (8) is provided. The rapid start-up voltage reference (8) includes a voltage reference circuit (10) operable responsive to a shut-down signal ENABLE. The shut-down signal has an enable state and a disable state. The voltage reference circuit (10) has a feedback loop (12) which has a first node (NODE 1). The voltage reference circuit (10) is operable to produce an output reference voltage (V.sub.REF) when the shut-down signal is in the enable state. A rapid start-up circuit (14) is coupled to the first node (NODE 1) and to a power supply node (V.sub.cc). The rapid start-up circuit (14) includes a capacitor (16) and is operable responsive to the shut-down signal to charge the capacitor (16) when the shut-down signal is in the disable state and to connect the capacitor (16) to the first node (NODE 1) when the shut-down signal is in the enable state.
