DALLAS--Texas Instruments Inc. here today unveiled a new complementary bipolar process technology that promises to increase the integration of digital CMOS logic with high-performance analog and mixed-signal functions by more than 20 times. TI said it plans to ship the first samples of chips produced with the new BiCom-II process in the second quarter this year.
"This process give TI the ability to combine much higher densities of digital logic on chip with leading-edge analog transistors--meaning smaller devices with more functionality and better performance," said Dan Reynolds, vice president for advanced analog products at TI. A key target for the BiCom-II process will be broadband communications.
The company said the bipolar portion of the new BiCMOS technology is a 15-volt process capable of making fast transistors for operational amplifiers, a key building block in analog functions. The CMOS portion provides 5- and 10-V analog transistors as well.
To increase the digital logic integration capability, TI has added a high-performance 5-V process module to the BiCom-II technology that will handle functions requiring thousands of gates. This capability boosts the integration capability by more than 20 times the gate density of previous complementary bipolar processes, according to TI.
In addition, TI said the BiCom-II technology handles thin-film resistors, dielectric isolation of transistors for improved noise immunity between analog and digital circuit blocks, and laser-trimmable metal links.
TI said it expects to be able to make higher performing components for cable and digital subscriber line (DSL) drivers and receivers, op amps, programmable gain amplifiers (PGAs) and other analog and mixed-signal blocks.
