Design structure for low voltage applications in an integrated circuit

摘要

A design structure that includes at least one tunneling device voltage reference circuit for use in low voltage applications is disclosed. The tunneling device voltage reference circuit includes a pair of voltage dividing device stacks, one having a linear voltage output and the other having a non-linear voltage output. A feedback circuit supplies a regulated voltage to each of the voltage dividing stacks so that the output voltages of the two device stacks equalize. Once the feedback circuit has locked, any one of the device stack output voltages and the regulated voltage may be used as a voltage reference.
