ABB operates by applying a bias voltage to the body terminal of a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor). The body bias voltage can be made more positive or negative to change the threshold voltage. A more positive body bias decreases the threshold voltage, enhancing the transistor's speed but increasing leakage. Conversely, a more negative body bias increases the threshold voltage, reducing leakage but slowing down the transistor. This dynamic adjustment allows for power-performance trade-offs tailored to specific applications or operational conditions.
