ABSTRACT
The Deeply Depleted Channel (DDC) transistor architecture offers 2 to 3 times improvement in body coefficient and 60 percent improvement in local mismatch in 55-nm technology, extending design techniques such as body biasing with voltage scaling to more recent technology nodes. This article presents a body bias architecture for adaptive correction of manufacturing variation, with less than 0.5 percent area penalty for the bias generators. Process monitors with digital readout independently detect p-channel MOS (PMOS) and n-channel MOS (NMOS) process windows. Fujitsu Semiconductor Limited offers DDC technology in its CS250S 55-nm production qualified process, and is currently in production with its first DDC product, a seventh-generation Milbeaut digital-camera processor that performs at twice the performance of the previous generation with 30 percent less power.
