摘要:
Circuits are disclosed providing uniform voltage swing across transmit switches for improved device performance. An integrated circuit (IC) formed on a die includes a switch having one or more field effect transistors (FETs) defining an RF signal path between an input port and an output port, each FET having a body node, and the switch being configured to be capable of being in ON and OFF states. The IC further includes a voltage distribution circuit coupled to the switch and configured to reduce voltage distribution variation across the switch, the voltage distribution circuit including one or more elements coupled to a selected body node of one or more FETs to reduce voltage distribution variation across the switch when the switch is in an ON state and is encountered by a respective RF signal at the input port.
