A digitally-controlled 20 b dynamic range BiCMOS stereo audio processor

BICMOS: From Dream to Reality

“…Within the project 412/2430 (1-5) the initial emphasis has been on the development of a first generation process (SICMOS1) and according demonstrators (6,7,16).…”

“…In the first phase of the project Philips demonstrated a hifi audio processor in a SICMOS1 technology (16).…”

Bipolar CMOS Esprit Project

“…Sy Philips the feasibility of the process has been demonstrated by a circuit of 20 K transistor complexity level cf. (1,20). Siemens has prepared the grounds for gate array IC's with on-chip memory function (2).…”
