High-precision design techniques in BiCMOS

The author discusses the utility of bipolar devices in high-accuracy, BiCMOS-based circuit design. Examples are given which exploit the greater stability, lower 1/f noise, and higher operating voltage of bipolar devices. The examples show that BiCMOS circuits easily extend the performance boundaries normally reached in CMOS-only design. Compared to pure CMOS, BiCMOS adds flexibility to high-precision circuit design, resulting in performance advances with shorter development time and lower risk.<
