Simplified bias scheme for digital designs

摘要

Structures for a circuit including field-effect transistors and methods for fabricating and operating such circuits. A plurality of logic cells with a first well and a second well. The first well is directly connected with ground. A tap cell includes an inverter having an output connected with the second well. The inverter is configured to provide a bias voltage having a first state in which a positive voltage is supplied to the second well and a second state in which the second well is connected with ground.
