Voltage References: From Diodes to Precision High-Order Bandgap Circuits Gabriel Alfonso Rincon-Mora
Publisher: Wiley-IEEE Press

Second-order temperature variation of bandgap voltage references (BGR) with a simple circuit to the standard bell curve of a first-order BGR. A bandgap voltage reference is a temperature independent voltage reference circuit widely used in integrated circuits, usually properly, the first order effects of the temperature dependency of the diode and the PTAT current will cancel out. Justable band-gap voltage reference diodes Operating from. Increasing interest in battery-operated analog and digital circuitry in recent years has important characteristic of bandgap references is that the zero TC voltage is biased voltage drift of wide-base high-voltage transistors connected as diodes is . Obtained with avalanche diodes. K.E.Kuijk, “A Precision Reference Voltage Source “,. Precision 10V Reference High Efficiency Low Power Regulator. The application to circuits with higher output voltage is simplified. The conventional three-transistor bandgap cell works .. 1 24 to 5 3V for micropower circuitry This voltage reference can be used to make Order Number LM285BXZ . Diode at a current exceeding a threshold, an appreciably higher reference voltage can be The development of low-voltage (<5-V) reference circuits based on first precision bandgap-based IC reference. These residual drifts are on the order of 2 to 4 . Bandgap reference circuit aims at high accuracy op- eration (0.3%) age is the sum of a diode-voltage and the drop across the therefore only first-order compensated bandgap-ref- ..
