Abstract:
Systems, methods, and devices to control a transistor to maintain one or more substantially constant characteristics while activated or deactivated are provided. One such system includes a transistor that receives an activation signal on a gate terminal to become activated during a first period and receives a deactivation signal on the gate terminal to become deactivated during a second period. The transistor receives an input signal on an input terminal during the first period and the second period. The input signal varies during the first period and during the second period. The transistor may have improved reliability (e.g., substantially constant on resistance RON) because a first difference between the input signal and the activation signal substantially does not vary during the first period and a second difference between the input signal and the deactivation signal substantially does not vary during the second period.
