Abstract

An apparatus for biasing ultra-low voltage logic circuits is disclosed. An integrated circuit device includes multiple transistors and a global body bias circuit. The global body bias circuit includes a first transistor and second transistors connected in series between a power supply and a second power supply or ground. The gate and source of the first transistor are connected to the first power supply. The gate and source of the second transistor are connected to the second power supply. The drains and bodies of the first and second transistors are connected together to form an output connected to the bodies of the other transistors within the integrated circuit device.
