摘要： A scalable periphery digital power control arrangement is presented. The scalable periphery digital power control arrangement comprises a plurality of PMOS transistors connected in parallel, where the plurality of transistors is operatively coupled to a voltage source. The plurality of PMOS transistors that is operatively coupled to the voltage source can operate as a controlled current source. Current flow from the voltage source can be controlled by a logic circuit, which sends a logic signal to enable or disable each individual PMOS transistor of the plurality of PMOS transistors connected in parallel. As more PMOS transistors are enabled, the current flow through the scalable periphery digital power control arrangement to the amplifier can increase.
