AN INTEGRATED RF SWITCHING CELL BUILT IN CMOS TECHNOLOGY AND UTILIZING A HIGH VOLTAGE INTEGRATED CIRCUIT DIODE WITH A CHARGE INJECTING NODE

摘要

An integrated CMOS diode with an injection ring that enables construction of anintegrated CMOS RF switch. Construction techniques of using a diffused n-wellresistor, parasitic capacitance and construction of the diode underneath a bonding inputpad contribute to performance of the switch as well as saving space needed toconstruct the switch.19
