Body Effect and Body Biasing
Effective threshold voltage management for reduced power consumption
Body effect refers to the change in the transistor threshold voltage (VT) resulting from a voltage difference between the transistor source and body. Because the voltage on the body affects the threshold voltage, the body can be thought of as a second gate that helps determine how the transistor turns on and off. Strong body effect enables a variety of effective body biasing techniques. SuVolta’s Deeply Depleted Channel™ (DDC) transistor technology enables better threshold voltage (VT) control through body biasing. This effective threshold voltage management enables lower power consumption and higher yields for deep submicron CMOS technologies.
