Abstract
Multi-level buffers for biasing of radio frequency (RF) switches are provided. An RF switching circuit that includes a field-effect transistor (FET) switch, an impedance, and a multi-level buffer that provides a switch control voltage to a gate of the FET through the impedance is disclosed. The multi-level buffer receives a control signal to turn on or off the FET switch. Additionally, the multi-level buffer is implemented with stacked inverters that operate using different clock signal phases to pulse the switch control voltage in response to a transition of the control signal to thereby shorten a delay in switching the FET switch.
