Abstract:
Disclosed is a transistor-based switch having an N number of main field-effect transistors (FETs) stacked in series such that a first terminal of a first main FET of the N number of main FETs is coupled to a first end node and a second terminal of an Nth main FET of the N number of main FETs is coupled to a second end node, wherein N is a finite number greater than five. The transistor-based switch further includes a gate bias network having a plurality of gate resistors, wherein individual ones of the plurality of gate resistors are coupled to gate terminals of the N number of main FETs. A common gate resistor is coupled between a gate control input and a gate control node of the plurality of gate resistors, and a capacitor is coupled between the gate control node and a switch path node of the main FETs.
