In this paper we report a new 12volt, high performance, highly competitive silicon complementary bipolar technology. NPN and vPNP devices have been fabricated with cut-off frequencies greater than 12GHz and breakdowns not less than 12volts. Two optimization techniques are discussed that can be used to improve the cut-off frequency of the vPNP device independently of the NPN. The resulting process is considered ideally suited to the manufacture of highly linear 1GHz operational amplifiers.
