Application of HICUM and TRADICA at JazzSemi 2002 BCTM HICUM User’s Meeting

2 Sept. 29, HICUM User’s Meeting History The HICUM model has been available at Rockwell  Conexant  Jazz since 1996 –In house implementation in Spectre-RF, Eldo, and MDS until 1999 –Public domain release in 1999 –Build-in model maintained (w. r. t. simulator updates) by Cadence. Parameter extraction infrastructure has been implemented in Matlab using Spectre-RF and TRADICA. TRADICA has been used as HICUM library generation and parameter predications.

3 Sept. 29, HICUM User’s Meeting Present Status JazzSemi has become a foundry since March JazzSemi releases SGPM and HICUM using TRADICA and existing infrastructure. JazzSemi has BiCMOS model library for a variety of processes: –BC30 (30 GHz Si BiCMOS on 0.35  m CMOS platform) –SiGe60 (70 GHz SiGe BiCMOS on 0.35  m CMOS platform) –SiGe120 (150 GHz SiGe BiCMOS on 0.18  m CMOS platform)
