Claim 10:
11. A method of compensating a radio frequency (RF) switch device comprising a first transistor and a second transistor forming a switchable current path, the method comprising:
causing a first current to flow between a body terminal of the first transistor and a drain terminal of the second transistor in a first direction and causing a second current to flow therebetween in a second direction opposite to the first direction, wherein the first current is larger than the second current;
using a first bootstrapping network having a first terminal directly coupled to a tap of a resistor divider including a first resistor and a second resistor and having a first divider terminal, a second divider terminal, and a tap defined at an interconnection of the first resistor and second resistor, the first divider terminal directly coupled to a drain terminal of the first transistor and the second divider terminal directly coupled to a source terminal of the first transistor, a second terminal of the first bootstrapping network coupled to a gate terminal of the first transistor, and a third terminal coupled to the body terminal of the first transistor,
establishing a low impedance path between a gate terminal and the body terminal of the first transistor during an OFF mode of operation of the RF switch device; and
establishing a high impedance path between the gate terminal and the body terminal of the first transistor during an ON mode of operation of the RF switch device.
