An integrated circuit includes a voltage reference circuit including a Zener diode having a first terminal coupled to a first node and a second terminal coupled to a first voltage supply terminal. A proportional to absolute temperature (PTAT) circuit is coupled at the first node and configured to...

This chapter presents a complete zener diode family tree. The characteristics of the zener diode are described. The zener diode is a two-terminal, single-junction semiconductor device that passes meaningful electrical current in only one direction and simultaneously provides a stable reference voltage ...

A voltage reference element such as a zener diode 1 is supplied with at least two different current values during time periods t<SB>1</SB>, t<SB>2</SB>. One value is an optimum bias current 8 which ensures desired reference voltage characteristics, and the other value 9 results in a ...
What is a Zener Diode? Definition A zener diode is a diode manufactured to have a specific reverse-breakdown voltage. Its most common use is as a voltage reference. When reverse biased through a resistor, a zener diode will allow enough current to establish its specified voltage. Find a ...
Surface zener diodes have several problems: They require breakdown voltages of greater than 5V, they are noisy, and they have poor short- and long-term voltage drift.Ron ManciniElectrical Design NewsThe ultimate zener-diode reference. Mancini,Ron. European Documentary Network . 2004...
