ABSTRACT:
A voltage generating apparatus is disclosed. The voltage generating apparatus includes a first N-type transistor and an enhancement MOSFET transistor. The first N-type transistor has a first drain/source coupled to a first voltage, a second drain/source generating a first output voltage, and a gate coupled to a second voltage. The enhancement MOSFET transistor has a first drain/source coupled to the second drain/source of the first N-type transistor, and a second drain/source and a gate coupled to a second voltage. The first N-type transistor is a depletion metal oxide semiconductor field effect transistor (MOSFET).
