Fully-differential reference voltage source. |
摘要 |
<p>The source is apt to generate a fully-differential reference voltage at the output terminals, whereto precisely-balanced loads are applied. The voltage reference is obtained from a bandgap voltage source fed with currents proportional to the temperature, in order to minimize thermal voltage variations. Suitable circuits for starting the normal source operation after switching on are also provided.</p> |
