ECE411_layout

For wide transistors we prefer,

• single contacts at edges of source and drains

• large contacts covering the whole source and drain

• many small contacts at the source and drain

Wide transistors are divided into fingers to

• help in matching

• reduce the capacitance

• increase gm

• improve aspect ratio of layout

Sources of error in resistor values affecting absolute accuracy include

• corners

• end contacts

• etching

• type of resistor

The capacitor with best linearity is

• MOM

• MIM

• POLY

• MOS

We can increase the inductance of the spiral inductor by

• Increasing turns ratio

• decreasing inductor area

• increasing spacing
