Can I read Precision Voltage Reference Circuit on EtoBox?

Precision Voltage Reference Circuit by Bodhayan Prasad is a document available to read on EtoBox.

What is Precision Voltage Reference Circuit about?

1) The document describes a precision reference voltage source based on the principle that the difference in base-emitter voltages of two identical transistors increases with temperature in a predictable way. 2) The circuit uses 8 pairs of integrated transistors to generate a nearly temperature-independent output voltage of 9.88V. Testing found the output voltage has a parabolic temperature characteristic with a peak of 300K as expected. 3) The source has low noise of 17uV rms, and long-term drift of 10
