Abstract :
Complementation silicon controlled rectifiers (CSCRs) with various novel layouts are designed in 0.18 ??m RF CMOS process, including general CSCR, strip CSCR (SCSCR), island-strip CSCR (ISCSCR) and island-block CSCR (IBCSCR). SCSCR has highest FOM; however, the ISCSCR has lowest parasitic capacitance. Appropriate division layout of the CSCRs should be addressed to achieve a balance between active area capacitance and edge capacitance.
