<p>A low voltage supply circuit supplies an internal supply voltage in an integrated circuit, while consuming very little stand-by current, and providing substantial driving power to maintain the internal supply nodes at the desired voltage level. The low voltage supply circuit includes a first branch and a second branch. The first branch includes a pull-up circuit (11), a first transistor (18), a second transistor (19), and a reference circuit (14), connected in series. The drain and the gate of the first transistor (18) are connected to a first node (13). The pull-up circuit (11) in the first branch is coupled between the first node (13) and power supply node (12). The drain and the gate of the second transistor (19), are connected to a second node (15). The reference circuit (14) is connected between ground supply node (34) of the integrated circuit and the second node (15), supplying a reference potential to the second node (15).</p> |
