Tutorial: Analog Circuit Design in Bipolar-CMOS-DMOS (BCD) Technologies

Bipolar-CMOS-DMOS (BCD) technologies enable applications of high industrial interest, whereby high-voltage and highpower circuits are combined with high-density digital logic on a single die, as in (audio) power amplifiers and switch-mode power supplies (SMPS). This tutorial addresses challenges of BCD design that are not usually encountered when designing in standard CMOS, e.g. crossing (multiple) voltage domains, parasitic bipolar activity with inductive loads, large operating supply voltage ranges and electrostatic discharge (ESD). The tutorial looks into the structure of BCD technologies and devices, as well as typical circuits, such as power switches, gate drivers, level shifters and bootstraps.
