A precision one-volt shunt reference
Derek F. Bowers · 2003
The shunt reference has for the most part been used where cost is the major concern in the choice of reference. As a result, the most prevalent shunt references have a voltage set to around the bandgap voltage of silicon ( /spl cong/ 1.2-1.25V) and poor precision in terms of slope impedance, initial tolerance and temperature coefficient. This paper describes a shunt reference with a nominal one volt output (a much more convenient value) coupled with greatly improved precision characteristics.
