Abstract
This chapter focuses on signal-processing circuits. Besides amplification and multiplication, various other signal-processing functions are a part of the analog circuit design repertoire. Most of these functions are nonlinear. Stable and accurate voltage sources are needed as references for measurement circuits and power supplies. The Zener diode is a simple voltage-reference device. Zener diodes combine two mechanisms: (1) tunneling and (2) avalanche breakdown. Tunneling has a negative TC, and avalanche has a positive TC. Zener diodes are noisy, especially at low currents. Consequently, they are bypassed with a capacitor. In integrated circuits (ICs), high-performance Zeners are built below the IC surface as subsurface Zeners, which are less noisy because surface effects are eliminated. Lateral ion-implanted Zeners have low-tolerance voltages and are commonly used as references in IC circuits. The three-terminal current-source IC has a bandgap cell and a transconductance amplifier with an output.
