摘要： As disclosed a power supply control system routing a first power supply (222) voltage (VA) to an output voltage supply node (150) includes a first compound switch circuit (230), which includes a first field effect transistor, FET, (Q1) where a drain of the first FET is connected to the first power supply voltage. The first compound switch circuit also includes a second FET (Q2). A source of the second FET is connected to a source of the first FET forming a first shared source node (236) of the FETs. A drain of the second FET is connected to the output voltage supply node. A gate of the first FET and a gate of the second FET are connected together to form a first shared gate node (238).
The power supply control system includes first voltage driving circuitry (210) charging a first bootstrap capacitor (224), when the first compound switch circuit is in an "off" state, by controlling a first DC switching device (240) to pull one end of the bootstrap capacitor, connected to the first shared source node (236), to ground. The other end of the first bootstrap capacitor is connected via a first diode (226) to a second power supply (220).
The first voltage driving circuitry provides an "on" gate-to-source voltage level to drive the first compound switch circuit into an "on" state by turning "off" the first DC switching device and connecting said other end of the first bootstrap capacitor to said first shared gate node.

摘要： A transmit receive switch circuit described in conjunction with embodiments of the present invention is a switch circuit that has a first MOSFET (MN1) and a second MOSFET (MN2), goes into a switch-off state at the time of transmission, and goes into a switch-on state at the time of reception, the first MOSFET (MN1) and the second MOSFET (MN2) being connected between an input terminal (SWIN) and an output terminal (SWOUT). The switch circuit includes a shunt circuit (SHNT) that is connected between a common gate (COMG) and a common source (COMS), the common gate being connected to the gates of the first and second MOSFETs, and the common source being connected to the sources of the first and second MOSFETs. When a signal having a negative voltage relative to a reference voltage is applied to the input terminal, a switch that temporarily turns on causes the shunt circuit to short-circuit the common gate and the common source.

摘要： Switches for use in RF devices are provided that offer a better balance of power losses and switching times than switches of the prior art. Switches of the present invention comprise a stack of transistors controlled a symmetric bias network. The stack of transistors includes an even number of transistors arranged in series, where every two successive transistors defines a pair. The bias network includes a symmetrically branching set of connections, where the gates of every pair of transistors are connected by a first connection having a first node, and two or more first nodes are connected by a second connection to a second node, and so forth. The symmetry of the bias network tends to reject even harmonics, and the rejection of even harmonics can be further enhanced by adding capacitors between the bias network and the stack of transistors at points of symmetry.
