11Analog ESD Library and Documents

11.1 Analog Design Library

In analog design technologies, the number of supported elements is significant [1, 2]. Analog and power technologies can support many power supply voltages leading to a large number of both passive and active elements. With the high number of power supply voltages, passive and active elements, the number of electrostatic discharge (ESD) devices and ESD circuits can also be significant [3–9]. With a large number of passive devices, active devices, and ESD networks, design errors can occur due to the following:

• Electrical overvoltage (EOV) and electrical overcurrent (EOC) of passive elements
• Electrical overstress (EOS) of active elements
• Misapplication and misuse of ESD circuits to analog circuits

For a bipolar-CMOS-DMOS (BCD) technology, the power supply voltage can range from low voltage CMOS to high voltage (HV) levels. For example, a 120 V BCD technology may support 1.8, 2.5, 5.0, 10, 16, 20, 25, 40, 60, and 120 V applications. For each one of these voltage application levels, there are both passive and active elements to support these voltages.

11.2 Analog Device Library: PASSIVE ELEMENTS

Analog device libraries of supported devices can include resistors, capacitors, and inductors. In this section, analog passive elements will be reviewed.

11.2.1 Resistors

High-precision resistors are needed in analog applications, which contain high degree of matching and wide resistance ranges. Resistors in analog circuits include:

• Polysilicon ...
