Abstract
A low voltage generating circuit has a first current mirror to provide a first stable current, a second current mirror coupled to the first current mirror and a voltage generating unit connected to the second current mirror. The second current mirror provides a second current that is proportional to the first current in the voltage generating unit. The voltage generating unit utilizes three resistors in a T-shaped configuration, wherein a voltage output is taken from the T-shaped configuration and can output a voltage value less than one volt.
