摘要： Disclosed is a circuit comprises a first switching transistor (106) and a second switching transistor (108). The first switching transistor and the second switching transistor are coupled in series between an input voltage (V
IN ) and ground and having a common node (Switch Node) there between to provide a switching output. A first switching circuit (120) selectively couples a gate (G
P ) of the first switching transistor to the input voltage and a first mid-level voltage supply (V
LS ). A second switching circuit (118) selectively couples a gate (G
N ) of the second switching transistor to a second mid-level voltage supply (V
HS ) and ground. A charge-recycling circuit is thereby connected to the gate of the first switching transistor, the gate of the second switching transistor, the first mid-level voltage supply, and the second mid-level voltage supply to selectively recycle charge between the first mid-level voltage supply and the second mid-level voltage supply.摘要翻译： 在一个实施例中，电路包括第一开关晶体管和第二开关晶体管。 第一开关晶体管和第二开关晶体管串联耦合在输入电压和地之间并且在它们之间具有公共节点以提供开关输出。 第一开关电路将第一开关晶体管的栅极选择性地耦合到输入电压和第一中间电平电压。 第二开关电路将第二开关晶体管的栅极选择性地耦合到第二中间电平电压源并接地。 电荷回收电路耦合到第一开关晶体管的栅极，第二开关晶体管的栅极，第一中间电平电压供应和第二中间电平电压，以选择性地在第一中间电平 电压供应和第二中间电压供应。

摘要： The present disclosure includes circuits that have a switching regulator and methods of operating the circuits. The switching regulator may receive a switching signal that has a switching frequency. The circuit also includes a monitor circuit to monitor the switching frequency, and includes a reconfigurable inductance coupled to an output of the switching regulator. The monitor circuit may change the reconfigurable inductance. The circuit includes an amplifier to receive an envelope tracking signal. An output of the amplifier is coupled to the output of the switching regulator to provide a power supply voltage. The circuit may further include a switching generator circuit to produce the switching signal for the switching regulator based on an output current of the amplifier. The monitor circuit may compare a frequency of the envelope tracking signal to the switching frequency of the switching signal and accordingly change the reconfigurable inductance.
