Circuit Measures Small Currents Referenced To High-Voltage Rails: 01/07/02 Electronic Design - Ideas for Design /  Designs that need to measure small signals riding on high-voltage power rails suggest the use of isolation devices.

IC Voltage Reference has 1 Ppm Per Degree Drift: National Semiconductor Application Notes,04-Nov-1995

Linear Brief 41 Precision Reference Uses Only Ten Microamperes: National Semiconductor Application Notes, 02-Mar-1999

References for a / D Converters: National Semiconductor Application Notes,04-Nov-1995

Regulator Makes Dual Tracking Reference: 11/07/96 EDN-Design Ideas

Supply circuitry selects main or backup voltage and disconnects load: 07/21/97 Electronic Design - Ideas for Design /  A complete portable-equipment power supply, suitable for systems that can be plugged into a docking station, is presented in this circuit idea.

Supply delivers pin programmable multiple references: 05/01/03  EDN-Design Ideas / In the circuit of Figure 1, the REF01, IC1, is a buried-zener-diode-based, precision 10V reference that features minimal noise and drift over temperature. The circuit provides not only the 10V output of the REF01, but also a 5V output that a REF02 reference would deliver.

Voltage Reference improves JFET: 10/26/00 EDN-Design Ideas /  PDF contains multiple circuits - scroll to find this circuit The common JFET current-source in Figure 1a has average output impedance and depends heavily on the JFET's V P and I DSS variations.
